<p>Jmandel: </p> <hr /> <div>The [https://github.com/openwfm/wrf-fire WRF-Fire] repository contained a complete copy of WRF, and the fire model files were provided to NCAR to be included in WRF, which was maintained in SVN at the time, and WRF file tree copied back into a subdirectory in WRF-Fire repository. After submitting the WRF 3.3 update in 2011, [[Changes in WRF-Fire 3.3 release|the files were changed from the submitted version]],and the yearly submission stopped. Over time, upgrading to new versions of WRF has become more difficult. <br /> <br /> Fortunately, the [https://github.com/wrf-model/WRF/commit/8fafea9e9922ec231dfb75e721f83ea78418b57d transition of WRF to GitHub] in 2016 presented an opportunity to make WRF-Fire into a fork of WRF.<br /> <br /> This was achieved in two stages:<br /> <br /> # The original [https://github.com/openwfm/wrf-fire WRF-Fire] repository used a different layout than WRF.

The fire spread is implemented by the [[wikipedia:Level set method|level set method]].

It is integrated as a physics option, called from WRF as a subroutine. It calls WRF libraries for utilities such as I/O and communication between [[MPI]] processes. The fire code executes on a part of the domain, called a tile (in WRF nomenclature).

The subroutines for the computation of the rate of spread and for the insertion of the heat flux to the atmosphere are taken from [[CAWFE]].

See &lt;code&gt;subroutine read_input_jet&lt;/code&gt;.<br /> <br /> This is as far as I want to go in ideal.exe, more complicated data input should be done through real.exe. <br /> <br /> [[User:Jmandel|Jmandel]] 01:29, 1 February 2010 (UTC)<br /> <br /> :Agreed. No reason to reinvent the wheel here.<br /> :[[User:Jbeezley|Jbeezley]] 02:41, 8 February 2010 (UTC)<br /> <br /> == Proposed computation of smooth terrain gradient ==<br /> <br /> Currently the terrain height zsf is given at the centers of the fire grid cells. The terrain gradient is then computed in Fire by central differences, and this is the gradient that enters in the Rothermel's formula. When the terrain height is interpolated from coarser data (by bilinear interpolation), the gradient is discontinuous at the fire mesh scale, which causes jumps in fire propagation. Instead, I propose:<br /> # The gradient components will be computed on a staggered grid directly from the data, on the mesh where the data is given. That is, the x-component of the gradient will be computed at midpoints in the x-direction between the data points by central differencing, and similarly the y-component of the gradient will be computed at midpoints the y-direction between the data points.<br /> # The two components of the gradient will be interpolated to the centers of the fire grid nodes by bilinear interpolation<br /> # Terrain height for the atmospheric model will be computed by bilinear interpolation from the data<br /> The staggered mesh where the gradient is computed in 1. is reminiscent of the staggered mesh WRF uses for the wind; in fact, the interpolation in 2. is exactly the same that I already use for the interpolation of the wind to the fire mesh. This should result in<br /> # Gradient as accurate as the resolution of the topography data allows, without an unnecessary loss of accuracy<br /> # Continous gradient, without any jumps<br /> # No artificial smoothing needed<br /> The terrain height data can/should be given in its native resolution, unrelated to the any model mesh sizes. This will be easy to handle when terrain data is loaded from a file in an ideal run. In a real run, it might be more appropriate to do this computation in WPS. <br /> [[User:Jmandel|Jmandel]] 00:48, 8 February 2010 (UTC)<br /> <br /> :I'm not sure that what you propose will actually eliminate the need for artificial smoothing. From what I have read, the data itself can be quite noisy with errors on the order of the horizontal resolution or more. WPS already handles these issues at the atmospheric grid level; it may be best to keep the computations there. What about:<br /> :# For ideal, the fire grid topography is read in just like the fuel category field (already processed to the fire grid). The user can do the smoothing and interpolation. Ideal will compute the gradients from this directly and populate the slope field.<br /> :# For real, the interpolation, smoothing, and gradient is computed with WPS. This is a trivial addition, nothing more than a few lines in a runtime parameter file. We would just need to modify the registry to mark the fire resolution slope field as input and restart. The fire code in &lt;code&gt;wrf.exe&lt;/code&gt; would procede assuming that these fields are already populated.<br /> :One complication for this would be that the gradients would be specified on cell centered grid. WRF and WPS have no concept of staggering on the fire grid.<br /> :[[User:Jbeezley|Jbeezley]] 02:41, 8 February 2010 (UTC)<br /> <br /> It would eliminate the need for artificial smoothing to get rid of the blockiness caused by coarse topography resolution, but of course the input of the altitude would be much simpler for me... and it would let the user deal with the smoothing issues. <br /> Terrain gradients from WPS at centers of the cells is precisely what is needed, thanks. No need for any staggered grid there.<br /> [[User:Jmandel|Jmandel]] 23:51, 8 February 2010 (UTC)<br /> <br /> Saved explanation, removed from the wish list: ''This will allow the gradient to be smoothly interpolated in preprocessing in the WPS or in setting up ideal cases. No artificial terrain smoothing is needed. The current scheme interpolates terrain height linearly, and if the mesh the terrain is interpolated from is much coarser than the fire mesh, this results in gradient jumps along the terrain mesh lines. Then, the fire spread rate jumps along the terrain mesh lines.'' [[User:Jmandel|Jmandel]] 20:48, 13 June 2010 (UTC)<br /> <br /> == Standalone driver ==<br /> <br /> This is how WRF-Fire was originally developed. The driver was phys/model_test_main.F until {{WRF-Fire-commit|a3f839e50ebcf7e068c8aa0266401220bc09f2ec|deleted in November 2008}}. The last commit with the driver working might be {{WRF-Fire-commit|135afed6783683d273b0eac9e0c1b959bd9e2351|this}}. It should be resurrected now after the long argument lists are cleaned up. What would the driver do for inputs and outputs? NetCDF? [[User:Jmandel|Jmandel]] 04:39, 30 May 2010 (UTC)<br /> <br /> :I think NetCDF would be best. In fact, I think we should maintain some sort of compatibility between these and WRF output files. This way, we can use existing visualization/data assimilation code. All this really requires is naming the variables and dimensions the same. [[User:Jbeezley|Jbeezley]] 07:55, 30 May 2010 (UTC)<br /> <br /> Re [http://www.openwfm.org/w/index.php5?title=WRF-Fire_development_notes&amp;diff=prev&amp;oldid=910 this edit]: Why would a standalone driver be for diagnostics only? Of course diagnostics would be the main purpose for us, but many models, such as [[FARSITE]], do not interface with atmosphere either. If we can run from the same data, it would be interesting to compare. I suppose this could be still called diagnostics, though. [[User:Jmandel|Jmandel]] 16:37, 5 June 2010 (UTC)<br /> <br /> The standalone model {{WRF-Fire-commit|168fbfaa8a62061b51999001dc55162e2ac3a798|now}} runs from WRF outputs, with additional fire mesh variables (wind interpolation, fuel data) added by preprocessing in the coupled fire model. For documentation, see [[How to run the standalone fire model in WRF-Fire]]. To do: another driver that would run only the preprocessing to take unmodified WRF output, add the fire variables, and create an input file to run the standalone code from. There is a hook in '''standalone/Makefile''' for '''atm.exe''' for this purpose already. Also, the utility '''init.exe''' to create to create a simple ideal example without WRF at all should be revived. [[User:Jmandel|Jmandel]] 20:01, 28 October 2011 (UTC)<br /> <br /> == Gradual ignition ==<br /> <br /> The current scheme requires that the ignition area is several fire mesh steps large. When such area ignites all at once, all the heat is output to the atmosphere at once, instead of being output gradually and allowing ground layer circulation to develop over time.<br /> * Very fine fire mesh simulation first to identify if there actually is a problem.<br /> [[User:Jmandel|Jmandel]] 19:06, 2 June 2010 (UTC)<br /> <br /> Kara Yedinak has asked some questions about ignition in [http://mailman.ucar.edu/pipermail/wrf-fire/2009-August/thread.html this thread] involving virtual ignition and Gaussian sources. I do not think I have done anything about it yet and I do not quite understand the issue (Gaussian sources of what? Heat output into the atmosphere?) Maybe this could be merged with/replace/clarify the gradual ignition. <br /> I have [http://www.openwfm.org/w/index.php5?title=WRF-Fire&amp;diff=924&amp;oldid=921 edited the line] for Kara in [[WRF-Fire#Contributors]] to replace &quot;exposed bugs contributing to a better fire initialization&quot; by &quot;suggestions for improvements&quot;. In any case I do not think I have made any such improvements yet. The above thread was all I could find now about the issue. Janice, if there were in fact some bugs and I forgot to do anything about them I'd like to know please. [[User:Jmandel|Jmandel]] 16:19, 5 June 2010 (UTC)<br /> <br /> ===Subscale ignition===<br /> <br /> Adam has noticed that the fire spread in the FireFlux sim is too fast. This appears to be at least partly because of the ignition and he got a better match with a smaller fire mesh step. But there are limits to how fine the fire mesh can be, even with Jon's {{WRF-Fire-commit|06c276f324873bc4c6f82c27298430435989ab97|latest improvement}} that allows an array in the NetCDF file to be over 2GB. There seem to be two reasons: 1. the ignition area is too large and it fires up all at once 2. in reality, a fire starts small, and only as the flame length grows, the wind-driven spread rate kicks in. Adam noted data that show that the spread rate starts slow and then goes up. One explanation would be that the spread rate depends on the flame length, and the flame length in turn increases with the mid-flame wind speed, so they feed on each other. Consequently, it can take a while before the fire is fully engaged (is ''engaged'' a technical term? I heard it in the [[Fourmile Canyon fire]]), yet the current model ignores that. To start, I'll just parametrize the spread rate as a linear function of distance from ignition until the full spread rate is reached.<br /> <br /> So, after [http://ccm.ucdenver.edu/wiki/Jan_Mandel/Blog/2010_Oct_Nov#October_6.2C_2010 floundering for weeks], I have finally made up my mind. Line ignition will be by imposing level set function/ignition time based on &lt;s&gt;the no-wind&lt;/s&gt; a given spread rate &lt;s&gt;for a number of seconds&lt;/s&gt; until the ignition radius given in the namelist. Advancing the level set equation will run concurrently, by taking the pointwise minimum of the existing level set function and the imposed one in each time step, much like [http://github.com/jbeezley/wrf-fire/blob/06c276f324873bc4c6f82c27298430435989ab97/wrfv2_fire/phys/module_fr_sfire_core.F#L200 the pointwise minimum I am doing now]. <br /> This will be called '''subscale ignition''' because the new parametrization is below the mesh resolution as well as below the model scale itself. <br /> <br /> [[User:Jmandel|Jmandel]] 17:39, 17 October 2010 (UTC)<br /> <br /> ===Parametrized ignition===<br /> <br /> Slow down the wind-driven spread rate by introducing new wind reduction factor: zero at the ignition line, 1 at a given distance from the ignition line. The distance will be measured as a combination of the distance to the nearest active point on the ignition line, and upwind distance. Taking upwind from the current point also avoid parallelism issues - we cannot go downwind from the ignition line because we cannot take info from the ignition line to other tiles, yet the level set function needs to be set on other tiles too. The distance from the ignition line where the full spread rate is reached will be a new property of fuel, and the weight in the mix between the nearest and upwind distance will be a parameter. <br /> <br /> Or just attenuate winds close to ignition point. <br /> <br /> [[User:Jmandel|Jmandel]] 23:12, 28 December 2010 (UTC)<br /> <br /> == Ugly includes ==<br /> <br /> Archived from the wish list: ''Remove the ugly includes in the argument lists to get the coefficients down the call chain to the spread rate calculations. Pass the coefficients by pointers defined in a module instead. Declare the pointers in the module, or pass them around in a single derived type argument. This is a necessary step before including the weather and fire components into [[VisTrails]] separately.'' (And also before reviving the standalone driver.) [[User:Jmandel|Jmandel]] 07:28, 14 June 2010 (UTC)<br /> <br /> == Surface Initialization ==<br /> <br /> By default, the atmospheric surface layer and the land surface models are turned off, and there is no control over the basic surface properties in the idealized runs. In particular, there is no way to define the roughness length (z0) affecting the wind profile, and the skin and soil temperatures (TSK and TMN) affecting the surface heat flux. In order to have more realistic surface winds and surface heat fluxes, improvements in surface initialization are needed. The goal here would be to use general WRF mechanisms for the surface initialization based on the atmospheric surface layer model and land surface models. The surface properties would be defined using the USGS classification and LANDUSE.TBL records. Using on of the land surface models would allow for heaving the surface temperature and surface heat fluxes dynamically affected by the fire [[User:Adamko|Adam Kochanski]] 11:55, 14 July 2010<br /> <br /> == Ignition Time ==<br /> <br /> Currently, the number of seconds elapsed from the start of the simulation is calculated as the &lt;code&gt;time_step * dt&lt;/code&gt; (see [http://github.com/jbeezley/wrf-fire/blob/5b0cf740a6c64af18a52be3f704581305a0e5406/wrfv2_fire/phys/module_fr_sfire_driver.F#L419 source]). This assumes &lt;code&gt;dt&lt;/code&gt; is constant. A correct implementation would use WRF domain time control derived types to query for the start time. For instance, the current simulation time is queried [http://github.com/jbeezley/wrf-fire/blob/5b0cf740a6c64af18a52be3f704581305a0e5406/wrfv2_fire/dyn_em/module_first_rk_step_part1.F#L211 here]. The start time for the current nest can be returned using the function &lt;code&gt;domain_get_start_time&lt;/code&gt; [http://github.com/jbeezley/wrf-fire/blob/5b0cf740a6c64af18a52be3f704581305a0e5406/wrfv2_fire/frame/module_domain.F#L1599 here] along with other useful time control subroutines. These functions return derived types based on [[wikipedia:ESMF|ESMF]] specifications. In particular, these derived types support common operators such as addition, subtraction, and comparison (&lt;code&gt;.le.&lt;/code&gt;, &lt;code&gt;.eq.&lt;/code&gt;, etc.). See implementation of these types [http://github.com/jbeezley/wrf-fire/blob/5b0cf740a6c64af18a52be3f704581305a0e5406/wrfv2_fire/external/esmf_time_f90/ESMF_Time.F90 here] and [http://github.com/jbeezley/wrf-fire/blob/5b0cf740a6c64af18a52be3f704581305a0e5406/wrfv2_fire/external/esmf_time_f90/ESMF_TimeInterval.F90 here]. (Note: WRF renames the types internally from &lt;code&gt;ESMF_Time&lt;/code&gt; to &lt;code&gt;WRFU_Time&lt;/code&gt;.)<br /> <br /> Another improvement over the current implementation would be to allow fire ignitions to occur in a restart run.

This will allow the atmosphere to evolve along with the growing fire. Also, this will provide some support for gradual ignition. [[User:Jmandel|Jmandel]] 05:23, 30 August 2010 (UTC)<br /> <br /> Actually, we can prescribe just the ignition time - and use it as the level set function itself also.

I did not do it this way because it is more complicated and computationally expensive that what is in the code now (interpolate to 6.1m, then use the wind reduction factors) and I did not know what the fuel height numbers might be and how to adjust the rest of the spread rate coefficients, but it is certainly better, particularly if the first few grid levels are below the 6.1m. Then it would make sense to also make the roughness height a part of the fuel description, we would need the fine resolution. [[User:Jmandel|Jmandel]] 05:01, 8 February 2011 (UTC)<br /> <br /> This has been in fact on the [http://www.openwfm.org/w/index.php5?title=WRF-Fire_development_notes&amp;oldid=1825#Back_burner back burner] as &quot;vertically interpolate the wind to different heights for different fuels&quot; already since [http://www.openwfm.org/w/index.php5?title=WRF-Fire_development_notes&amp;oldid=1665#Back_burner November 2010]. Putting back on the wish list now. [[User:Jmandel|Jmandel]] 12:49, 15 February 2011 (UTC)<br /> <br /> Done {{WRF-Fire-commit|72219b996f0dbe6af16cd7afdcc39e036c751156|24 Feb 2011}} by interpolating log interpolation of the horizontal wind vertically in the column above a fire mesh node, computing horizontally interpolated wind and geopotential to the height needed to save computations and memory. Previous code remains see option 4 below. Unless the wind and the geopotential are extended in-array one beyond the domain (I hesitate to mess with that) the price is I get zero spread rate in a layer of half atmosphere cell wide around domain boundary, which fortunately does not matter. {{WRF-Fire-commit|f28515b883bb8df682e0b8029f85cf88bfb6ea83|31 Mar 2011}}: minor changes, simplified interface, tested, merged into master [[User:Jmandel|Jmandel]] 20:20, 31 March 2011 (UTC)<br /> <br /> ===How is the wind interpolation implemented===<br /> The type of interpolation is set in namelist.input by '''fire_wind_log_interp''' which controls the roughness height '''fz0''' and the height '''fwh''' to interpolate the wind to. The interpolated wind is multiplied by the reduction factor '''windrf''' from fuel category description in namelist.input<br /> * '''fire_wind_log_interp=1''': '''fz0''' and '''fwh''' are taken from fuel description.<br /> * '''fire_wind_log_interp=2''': '''fz0''' is interpolated piecewise constant from '''z0''' in landuse, '''fwh''' is taken from fuel description.<br /> * '''fire_wind_log_interp=3''': '''fz0''' is interpolated bilinearly from '''z0''' in landuse, '''fwh''' is taken from fuel description.<br /> * '''fire_wind_log_interp=4''': vertical interpolation on the atmosphere mesh using '''z0''' from landuse to '''fire_wind_height=6.096m''' then interpolate to the fire mesh. This is the default (previous code).<br /> <br /> All options give essentially the same results with the defaults as set in the code (assuming fz0 is set in the fuel categories to the same as z0 and the ground is flat). Using log interpolation is important because that makes the code work even with the first level when u,v winds are known is above the desired height to interpolate to. In fact if the wind profile actually is logarithmic with the specific roughness length then the resulting wind that goes to the spread formula does not depend on the vertical spacing of the atmospheric grid.

A minimal empirical moisture model might be<br /> # Equilibrium moisture as a function of humidity, temperature, and solar radiation from WRF. <br /> # The fuel moisture approximates the equilibrium with a time lag. The time lag might also be a function of WRF variables (wind).<br /> # Rain adds moisture at a rate that increases with rain intensity. But the rate does not increase over a given max. absorption rate and the fuel moisture cannot go over a given max moisture. No time lag.<br /> # The coefficients of all the model functions given in fuel categories, should be derived from published tables and graphs.<br /> # Moisture and fire models can be turned on and off independently.<br /> # Fire can take moisture from direct coupling, or from an earlier run and interpolate in time. Perhaps add several moisture fields with different names to wrfinput/wrfout. Avoid fire mesh sized arrays with a 3rd dimension because of 32bit limits.<br /> [[User:Jmandel|Jmandel]] 02:51, 11 September 2011 (UTC)<br /> <br /> Moisture model runs on the atmospheric grid, independently for one or more of fuel classes. Each class can have its own model or parameters of the model. Currently, a fine fuels model calibrated on the Canadian fire danger rating system is implemented similar to the above. The moisture contents in the fuel classes is combined in different proportions for different fuel categories, and interpolated to the fire grid. If the moisture model does not run, the interpolation takes the moisture contents in the fuel classes from wrfinput.

The fire model results are bitwise identical even if the restart is in the middle of an ignition. However, WRF will pass to the fire model slightly different atmospheric state than if the run just continues without a restart. The first variable that is different is '''rho''', by about 1%. This has a very minor effect on the insertion of fire heat fluxes into the atmosphere. The results will not be bitwise identical. <br /> It should be OK to change the fuel properties in '''namelist.fire''', but changes in '''namelist.input''' might have unpredictable consequences.

<p>Jmandel: rm {{software}}</p> <hr /> <div>{{historical|WRF-SFIRE user guide}}<br /> : ''The code under continued development in our repository and mirrors [http://repo.or.cz/git-browser/by-commit.html?r=wrffire.git] [https://github.com/jbeezley/wrf-fire/] is called '''[[SFIRE]]''', and the coupled code is called [[WRF]] and [[SFIRE]]. We reserve the designation [[WRF-Fire]] for the [[fire code in WRF release|version released with WRF]].''<br /> <br /> '''WRF-Fire''' combines the Weather Research and Forecasting model ([[WRF]]) with a fire code implementing a surface fire behavior model, called [[SFIRE]], based on semi-empirical formulas calculate the rate of spread of the fire line (the interface between burning and unignited fuel) based on fuel properties, wind velocities from WRF, and terrain slope. The fire spread is implemented by the [[wikipedia:Level set method|level set method]]. The heat release from the fire line as well as post-frontal heat release feeds back into WRF dynamics, affecting the simulated weather in the vicinity of the fire. The fire code is written in [[wikipedia:Fortran|Fortran 90]] following [http://www.mmm.ucar.edu/wrf/WG2/WRF_conventions.html WRF coding conventions]. It is integrated as a physics option, called from WRF as a subroutine. It calls WRF libraries for utilities such as I/O and communication between [[MPI]] processes. The fire code executes on a part of the domain, called a tile (in WRF nomenclature). All communication between the tiles is in the caller; thus, one time step requires multiple calls to WRF-Fire. <br /> <br /> WRF-Fire is essentially a reimplementation of [[CAWFE]] with the weather model replaced by WRF and with the fire spread implemented by the level set method in SFIRE. The subroutines for the computation of the rate of spread and for the insertion of the heat flux to the atmosphere are taken from [[CAWFE]].

See &lt;code&gt;subroutine read_input_jet&lt;/code&gt;.<br /> <br /> This is as far as I want to go in ideal.exe, more complicated data input should be done through real.exe. <br /> <br /> [[User:Jmandel|Jmandel]] 01:29, 1 February 2010 (UTC)<br /> <br /> :Agreed. No reason to reinvent the wheel here.<br /> :[[User:Jbeezley|Jbeezley]] 02:41, 8 February 2010 (UTC)<br /> <br /> == Proposed computation of smooth terrain gradient ==<br /> <br /> Currently the terrain height zsf is given at the centers of the fire grid cells. The terrain gradient is then computed in Fire by central differences, and this is the gradient that enters in the Rothermel's formula. When the terrain height is interpolated from coarser data (by bilinear interpolation), the gradient is discontinuous at the fire mesh scale, which causes jumps in fire propagation. Instead, I propose:<br /> # The gradient components will be computed on a staggered grid directly from the data, on the mesh where the data is given. That is, the x-component of the gradient will be computed at midpoints in the x-direction between the data points by central differencing, and similarly the y-component of the gradient will be computed at midpoints the y-direction between the data points.<br /> # The two components of the gradient will be interpolated to the centers of the fire grid nodes by bilinear interpolation<br /> # Terrain height for the atmospheric model will be computed by bilinear interpolation from the data<br /> The staggered mesh where the gradient is computed in 1. is reminiscent of the staggered mesh WRF uses for the wind; in fact, the interpolation in 2. is exactly the same that I already use for the interpolation of the wind to the fire mesh. This should result in<br /> # Gradient as accurate as the resolution of the topography data allows, without an unnecessary loss of accuracy<br /> # Continous gradient, without any jumps<br /> # No artificial smoothing needed<br /> The terrain height data can/should be given in its native resolution, unrelated to the any model mesh sizes. This will be easy to handle when terrain data is loaded from a file in an ideal run. In a real run, it might be more appropriate to do this computation in WPS. <br /> [[User:Jmandel|Jmandel]] 00:48, 8 February 2010 (UTC)<br /> <br /> :I'm not sure that what you propose will actually eliminate the need for artificial smoothing. From what I have read, the data itself can be quite noisy with errors on the order of the horizontal resolution or more. WPS already handles these issues at the atmospheric grid level; it may be best to keep the computations there. What about:<br /> :# For ideal, the fire grid topography is read in just like the fuel category field (already processed to the fire grid). The user can do the smoothing and interpolation. Ideal will compute the gradients from this directly and populate the slope field.<br /> :# For real, the interpolation, smoothing, and gradient is computed with WPS. This is a trivial addition, nothing more than a few lines in a runtime parameter file. We would just need to modify the registry to mark the fire resolution slope field as input and restart. The fire code in &lt;code&gt;wrf.exe&lt;/code&gt; would procede assuming that these fields are already populated.<br /> :One complication for this would be that the gradients would be specified on cell centered grid. WRF and WPS have no concept of staggering on the fire grid.<br /> :[[User:Jbeezley|Jbeezley]] 02:41, 8 February 2010 (UTC)<br /> <br /> It would eliminate the need for artificial smoothing to get rid of the blockiness caused by coarse topography resolution, but of course the input of the altitude would be much simpler for me... and it would let the user deal with the smoothing issues. <br /> Terrain gradients from WPS at centers of the cells is precisely what is needed, thanks. No need for any staggered grid there.<br /> [[User:Jmandel|Jmandel]] 23:51, 8 February 2010 (UTC)<br /> <br /> Saved explanation, removed from the wish list: ''This will allow the gradient to be smoothly interpolated in preprocessing in the WPS or in setting up ideal cases. No artificial terrain smoothing is needed. The current scheme interpolates terrain height linearly, and if the mesh the terrain is interpolated from is much coarser than the fire mesh, this results in gradient jumps along the terrain mesh lines. Then, the fire spread rate jumps along the terrain mesh lines.'' [[User:Jmandel|Jmandel]] 20:48, 13 June 2010 (UTC)<br /> <br /> == Standalone driver ==<br /> <br /> This is how WRF-Fire was originally developed. The driver was phys/model_test_main.F until {{WRF-Fire-commit|a3f839e50ebcf7e068c8aa0266401220bc09f2ec|deleted in November 2008}}. The last commit with the driver working might be {{WRF-Fire-commit|135afed6783683d273b0eac9e0c1b959bd9e2351|this}}. It should be resurrected now after the long argument lists are cleaned up. What would the driver do for inputs and outputs? NetCDF? [[User:Jmandel|Jmandel]] 04:39, 30 May 2010 (UTC)<br /> <br /> :I think NetCDF would be best. In fact, I think we should maintain some sort of compatibility between these and WRF output files. This way, we can use existing visualization/data assimilation code. All this really requires is naming the variables and dimensions the same. [[User:Jbeezley|Jbeezley]] 07:55, 30 May 2010 (UTC)<br /> <br /> Re [http://www.openwfm.org/w/index.php5?title=WRF-Fire_development_notes&amp;diff=prev&amp;oldid=910 this edit]: Why would a standalone driver be for diagnostics only? Of course diagnostics would be the main purpose for us, but many models, such as [[FARSITE]], do not interface with atmosphere either. If we can run from the same data, it would be interesting to compare. I suppose this could be still called diagnostics, though. [[User:Jmandel|Jmandel]] 16:37, 5 June 2010 (UTC)<br /> <br /> The standalone model {{WRF-Fire-commit|168fbfaa8a62061b51999001dc55162e2ac3a798|now}} runs from WRF outputs, with additional fire mesh variables (wind interpolation, fuel data) added by preprocessing in the coupled fire model. For documentation, see [[How to run the standalone fire model in WRF-Fire]]. To do: another driver that would run only the preprocessing to take unmodified WRF output, add the fire variables, and create an input file to run the standalone code from. There is a hook in '''standalone/Makefile''' for '''atm.exe''' for this purpose already.

I do not think I have done anything about it yet and I do not quite understand the issue (Gaussian sources of what? Heat output into the atmosphere?) Maybe this could be merged with/replace/clarify the gradual ignition. <br /> I have [http://www.openwfm.org/w/index.php5?title=WRF-Fire&amp;diff=924&amp;oldid=921 edited the line] for Kara in [[WRF-Fire#Contributors]] to replace &quot;exposed bugs contributing to a better fire initialization&quot; by &quot;suggestions for improvements&quot;. In any case I do not think I have made any such improvements yet. The above thread was all I could find now about the issue. Janice, if there were in fact some bugs and I forgot to do anything about them I'd like to know please. [[User:Jmandel|Jmandel]] 16:19, 5 June 2010 (UTC)<br /> <br /> ===Subscale ignition===<br /> <br /> Adam has noticed that the fire spread in the FireFlux sim is too fast. This appears to be at least partly because of the ignition and he got a better match with a smaller fire mesh step. But there are limits to how fine the fire mesh can be, even with Jon's {{WRF-Fire-commit|06c276f324873bc4c6f82c27298430435989ab97|latest improvement}} that allows an array in the NetCDF file to be over 2GB. There seem to be two reasons: 1. the ignition area is too large and it fires up all at once 2. in reality, a fire starts small, and only as the flame length grows, the wind-driven spread rate kicks in. Adam noted data that show that the spread rate starts slow and then goes up. One explanation would be that the spread rate depends on the flame length, and the flame length in turn increases with the mid-flame wind speed, so they feed on each other. Consequently, it can take a while before the fire is fully engaged (is ''engaged'' a technical term? I heard it in the [[Fourmile Canyon fire]]), yet the current model ignores that. To start, I'll just parametrize the spread rate as a linear function of distance from ignition until the full spread rate is reached.<br /> <br /> So, after [http://ccm.ucdenver.edu/wiki/Jan_Mandel/Blog/2010_Oct_Nov#October_6.2C_2010 floundering for weeks], I have finally made up my mind. Line ignition will be by imposing level set function/ignition time based on &lt;s&gt;the no-wind&lt;/s&gt; a given spread rate &lt;s&gt;for a number of seconds&lt;/s&gt; until the ignition radius given in the namelist. Advancing the level set equation will run concurrently, by taking the pointwise minimum of the existing level set function and the imposed one in each time step, much like [http://github.com/jbeezley/wrf-fire/blob/06c276f324873bc4c6f82c27298430435989ab97/wrfv2_fire/phys/module_fr_sfire_core.F#L200 the pointwise minimum I am doing now]. <br /> This will be called '''subscale ignition''' because the new parametrization is below the mesh resolution as well as below the model scale itself. <br /> <br /> [[User:Jmandel|Jmandel]] 17:39, 17 October 2010 (UTC)<br /> <br /> ===Parametrized ignition===<br /> <br /> Slow down the wind-driven spread rate by introducing new wind reduction factor: zero at the ignition line, 1 at a given distance from the ignition line. The distance will be measured as a combination of the distance to the nearest active point on the ignition line, and upwind distance. Taking upwind from the current point also avoid parallelism issues - we cannot go downwind from the ignition line because we cannot take info from the ignition line to other tiles, yet the level set function needs to be set on other tiles too. The distance from the ignition line where the full spread rate is reached will be a new property of fuel, and the weight in the mix between the nearest and upwind distance will be a parameter. <br /> <br /> Or just attenuate winds close to ignition point. <br /> <br /> [[User:Jmandel|Jmandel]] 23:12, 28 December 2010 (UTC)<br /> <br /> == Ugly includes ==<br /> <br /> Archived from the wish list: ''Remove the ugly includes in the argument lists to get the coefficients down the call chain to the spread rate calculations.

[[User:Jmandel|Jmandel]] 07:28, 14 June 2010 (UTC)<br /> <br /> == Surface Initialization ==<br /> <br /> By default, the atmospheric surface layer and the land surface models are turned off, and there is no control over the basic surface properties in the idealized runs. In particular, there is no way to define the roughness length (z0) affecting the wind profile, and the skin and soil temperatures (TSK and TMN) affecting the surface heat flux. In order to have more realistic surface winds and surface heat fluxes, improvements in surface initialization are needed. The goal here would be to use general WRF mechanisms for the surface initialization based on the atmospheric surface layer model and land surface models. The surface properties would be defined using the USGS classification and LANDUSE.TBL records. Using on of the land surface models would allow for heaving the surface temperature and surface heat fluxes dynamically affected by the fire [[User:Adamko|Adam Kochanski]] 11:55, 14 July 2010<br /> <br /> == Ignition Time ==<br /> <br /> Currently, the number of seconds elapsed from the start of the simulation is calculated as the &lt;code&gt;time_step * dt&lt;/code&gt; (see [http://github.com/jbeezley/wrf-fire/blob/5b0cf740a6c64af18a52be3f704581305a0e5406/wrfv2_fire/phys/module_fr_sfire_driver.F#L419 source]). This assumes &lt;code&gt;dt&lt;/code&gt; is constant. A correct implementation would use WRF domain time control derived types to query for the start time. For instance, the current simulation time is queried [http://github.com/jbeezley/wrf-fire/blob/5b0cf740a6c64af18a52be3f704581305a0e5406/wrfv2_fire/dyn_em/module_first_rk_step_part1.F#L211 here].

These functions return derived types based on [[wikipedia:ESMF|ESMF]] specifications. In particular, these derived types support common operators such as addition, subtraction, and comparison (&lt;code&gt;.le.&lt;/code&gt;, &lt;code&gt;.eq.&lt;/code&gt;, etc.).

For every fuel, list the height to take the wind from and interpolate there at every fire mesh node directly. This would be similar as in [[CAWFE]], which makes the grid level to take the wind from (fuel height) a part of the fuel description. I did not do it this way because it is more complicated and computationally expensive that what is in the code now (interpolate to 6.1m, then use the wind reduction factors) and I did not know what the fuel height numbers might be and how to adjust the rest of the spread rate coefficients, but it is certainly better, particularly if the first few grid levels are below the 6.1m. Then it would make sense to also make the roughness height a part of the fuel description, we would need the fine resolution.

Previous code remains see option 4 below. Unless the wind and the geopotential are extended in-array one beyond the domain (I hesitate to mess with that) the price is I get zero spread rate in a layer of half atmosphere cell wide around domain boundary, which fortunately does not matter. {{WRF-Fire-commit|f28515b883bb8df682e0b8029f85cf88bfb6ea83|31 Mar 2011}}: minor changes, simplified interface, tested, merged into master [[User:Jmandel|Jmandel]] 20:20, 31 March 2011 (UTC)<br /> <br /> ===How is the wind interpolation implemented===<br /> The type of interpolation is set in namelist.input by '''fire_wind_log_interp''' which controls the roughness height '''fz0''' and the height '''fwh''' to interpolate the wind to. The interpolated wind is multiplied by the reduction factor '''windrf''' from fuel category description in namelist.input<br /> * '''fire_wind_log_interp=1''': '''fz0''' and '''fwh''' are taken from fuel description.<br /> * '''fire_wind_log_interp=2''': '''fz0''' is interpolated piecewise constant from '''z0''' in landuse, '''fwh''' is taken from fuel description.<br /> * '''fire_wind_log_interp=3''': '''fz0''' is interpolated bilinearly from '''z0''' in landuse, '''fwh''' is taken from fuel description.<br /> * '''fire_wind_log_interp=4''': vertical interpolation on the atmosphere mesh using '''z0''' from landuse to '''fire_wind_height=6.096m''' then interpolate to the fire mesh. This is the default (previous code).<br /> <br /> All options give essentially the same results with the defaults as set in the code (assuming fz0 is set in the fuel categories to the same as z0 and the ground is flat). Using log interpolation is important because that makes the code work even with the first level when u,v winds are known is above the desired height to interpolate to. In fact if the wind profile actually is logarithmic with the specific roughness length then the resulting wind that goes to the spread formula does not depend on the vertical spacing of the atmospheric grid.
