Unrealistically Low PM 2.5 concentration

Post by ganesh_Mk » Mon Sep 09, 2019 8:32 am

I am conducting experimental simulations to study the PM 2.5 concentration. I used the radm2/Made/Sorgam aerosol chemistry option (Chem_opt = 2). The simulation was successful but I am getting very low values of PM 2.5 of the order of 0.1 to 0.9 ugm-3 which should be of the order 100 to 900 ugm-3. I am confused as to where I am making mistake. has anyone come across similar kind of issue with PM 2.5 concentration?. what should be my next step in resolving this issue?.

I am attaching a time-series plot of PM 2.5 concentration and my namelist file for your reference.

Thank you. regards
