Radiation Driver failure in wrf.exe while using WRFV4.4

Hi,

I'm running WRF V4.4 for 18km,3km and 2km triple nested domain in Himalayan region. I'm using Thomson aerosol aware microphysics, KIAPS SAS cumulus, noah lsm, MYJ pbl, TKE_PBL sfc lay. I tried varous radiation options for SW and LW. However, wrf.exe fails every time radiation scheme is called. I am unable to figure out why this is happening. Can someone suggest a fix for this? I'm attaching namelist and error files below

Thanks
Suma

Hi,
Can you package all error files (e.g., rsl.error.*) into a single. tar file (not .rar file - we can't open those) and attach them here so I can see the full error at once? Thanks!
 
Hi kwerner,

I resolved this by increasing the epssm to 0.9 in the 2km domain.
Found this on one of the threads in WRF forum.

Thanks,
suma
