| Variable name | Default Value | Description |
|---|---|---|
| &domains | Domain control | |
| sr_x | 10 | Fire mesh is 10 times finer than the innermost atmospheric mesh in the x direction. This number must be even. |
| sr_y | 10 | Fire mesh is 10 times finer than the innermost atmospheric mesh in the y direction. This number must be even. |
| &fire | Fire control | |
| ifire | 0 | The fire model does not run |
| 2 | The fire model runs | |
| fire_fuel_read | -1 | -1 real fuel data from WPS |
| 0: set to fire_fuel_cat everywhere | ||
| 1: vegetation by altitude for testing | ||
| 2: read from file (ideal run only) | ||
| fire_num_ignitions | 3 | Number of ignition lines, max. 5 allowed |
| fire_ignition_ros1 | 0.01 | Rate of spread during ignition until the specified radius is reached |
| fire_ignition_start_x1 | 1000. | x coordinate of the start point of the ignition line 1. All ignition coordinates are given in m from the lower left corner of the innermost domain |
| fire_ignition_start_y1 | 500. | x coordinate of the start point of the ignition line 1. |
| fire_ignition_end_x1 | 1000. | y coordinate of the end point of the ignition line 1. Point ignition (spreading to a small circle) is obtained by specifying the end point the same as the start point. |
| fire_ignition_end_y1 | 1900. | y coordinate of the end point of the ignition line 1 |
| fire_ignition_radius1 | 18. | Everything within this radius from the ignition location will be ignited. |
| fire_ignition_start_time1 | 2. | Time of ignition in s since the start of the run, at the start point of the ignition line. |
| fire_ignition_end_time1 | 502. | Time of ignition at the end point of the ignition line. The time is linearly interpolated in between. |
| fire_ignition_ros2 | Up to 5 ignition lines may be given. Ignition parameters with the number higher than fire_num_ignitions are not allowed. | |
| … | ||
| fire_ignition_end_time5 | ||
| fire_print_msg | 1 | 0: no messages from the fire scheme |
| 1: progress messages from the fire scheme | ||
| fire_print_file | 0 | 0: no files written (leave as is) |
| >0: write fire model debug files | ||
| fire_wind_height | 6.096 | The height the fire spread formula takes the wind from (m) |
There are several more variables in the namelist for setting up various experiments, and then variables for developers’ use only to further develop and tune the numerical methods. Leave the variables for the developers as they are, unless directed by the developers.
