    Segmentation fault for wrf-chem when changing e_we and e_sn

    I'm running WRF452 on the Linux system in my own pc to simulate a typhoon. Wrf.exe runs successfully when e_we=27, e_sn= 27. However, when I replaced them with e_we=270, e_sn= 270, wrf.exe runs several hours and output 10 hours wrf_out* data, then it collapses with the following error...

    Why the concentrations of PM10 and PM2.5 in the wrfout file are identical with chem_opt=202 ?

    Hi everyone, I am currently running WRF-CHEM 4.2 with chem_opt=202, emiss_opt=3, and emiss_inpt_opt=111. I use emiss_opt=3 because the anthropogenic emission data I downloaded, MEIC, is for the RADM2 mechanism. I have observed that the concentration of PM10 in the wrfchemi file is greater...
