Hi all,
In my simulation, I found that the PM2_5_dry (and PM10) concentrations are always zero at the initial time step of WRF-Chem output file. For example, if I initialized my WRF-Chem run at 07/25 00UTC, the PM2_5_dry (and PM10) in wrfout_dxx_xxxx-07-25_00:00:00 are all zeros across whole domain.
However, the species used to compute PM2_5_dry such as OC1, OC2 are nonzero in the my wrfinput file, so I am just wondering is there anything wrong in my model setup or is there any suggestion for tacking this problem?
P.S. my WRF-Chem version is 3.9.1.1 and chem_opt = 112.
Thank you for your help
