Hello members,

I am running the WRF-Chem V3.5 using the RACM Chemistry and MADE/VBS aerosols (chem_opt=108). However, all values of EXTCOF55 are 'nan' after my simulation without any error message. I am not sure which part goes wrong. Would anyone please kindly give me some suggestions on this issue?

Thanks a lot in advance.


Looking at your namelist, don't use seas_opt = 2 it is disabled I believe. Use seas_opt = 1. Try to turn off gas phase chemistry gaschem_onoff = 0 and see if it helps to debug.
