	: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)		:I think NetCDF would be best.

	Re [http://www.openwfm.org/w/index.php5?title=WRF-Fire_development_notes&diff=prev&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.

	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 ~~examples~~ without WRF at all should be revived.
