Hello,
I am having some trouble including photolysis in the simulation. I have turned on photolysis and emissions in the name list. I can see my primary pollutants (NO, CO, SO2, PM, etc) concentration changes after the simulation, but photolysis doesn't seem to work in the current setting -- my NO2 and O3 concentration have no changes at all compared to the simulation that has no emissions. I have checked the default photolysis diagnostics, PHOTR201, 202 and 203 and they are all zero.
I am wondering if I could get any suggestions on what could possibly lead to this failure to include photolysis, or how I could approach this problem? I appreciate your help!
