All other topics about postprocessing model data (GrADS and other software), about other numerical weather prediction software (including WRF-NMM and WRF-ARW discussion unrelated to UEMS/WRF EMS), and general meteorology talk go in this forum.
Does anyone know what are all requirements to meet in order to have lightning data in gribs apart from microphysics scheme turned on (does any work?), do_radar_ref=1 and lightning_option=1, also in wrf_cntrl.parm:
Wow, I did not know that this field exists, I have never tried this. Did you find any solution in the mean time? Will this output the lightning probability in percent?
It requires fixed time step AND cu_physics = 5. And then you get pretty much same areas as high radar reflectivity and/or high updraft areas, because those schemes use that parameters to forecast lightning. I don't think it is worth it. Just use reflectivity or vertical speed to do the same...
MAYBE in EMS code is improved in a way to be able to use adaptive or other cu_physics. I don't know. Try...
