Hello everyone,
I’m a new user of CMAQ. I really need some help. The version I am using is CMAQv5.5_cb6r5_ae7_aq_m3dry, and I want to calculate the total concentration of SOA. After running “Combine”, I obtained a variable named ASOMIJ. According to some previous posts on this forum, ASOMIJ represents the total concentration of SOA. Is my understanding correct? If so, the ASOMIJ value I calculated seems a bit too high. My simulation region is located in East Asia. According to some literature, the maximum SOA concentration in this region should be around 5 μg/m³, but my simulation results are approximately 10 times the normal value. I’m new to this and I don’t know what mistake I made. I would be grateful for any replies.
