I have some questions about process analysis in CMAQ version 5.3.1.
I think ‘AERO’ process is meaning contribution of gas-phase chemical reaction.
But I confirmed that the minimum value of ‘AERO_ASO4I’ in my simulation represented negative value.
I want to know why negative value can be shown in AERO process.
And If my thinking (AERO process means gas-phase chemical reaction) is wrong, then how I can get contribution of gas phase chemical reaction in process analysis??
I hope that I get answers from you.
