I have a question related to Sulfur Tracking Model(STM) species.
There are several species such as ‘ASO4AQH2O2J’, ‘ASO4AQGASI’, ‘ASO4AQFEMNJ’, ‘ASO4EMISJ’ etc.
Then, can I call these STM species ‘counter species’ in CMAQ ??
I’ve read CMAQ science documentation chapter 8 and 10.
And ‘counter species’ and ‘aerosol yields’ were introduced in these documentations.
So, I thought that STM species could be called ‘counter species’ or ‘aerosol yields’ in CMAQ.
But I’m so confused because I don’t know which one is correct.
Also, I want to know calculation method of these species concentration.
For example, in case of H2O2 aqueous-phase reaction of sulfate formation,
I think that ‘ASO4AQH2O2J’ concentration is calculated by a reaction such as
‘SO2 + H2O2 --> ASO4AQH2O2J+H2O’ in CMAQ chemical mechanism.
I want to know whether my thinking is right or not.
So, If you guys know about that, please let me know.
Thank you for your replying
But I want to know whether STM species such as ‘ASO4AQH2O2J’ is calculated by independent reaction not ‘ASO4’ formation reaction.
So, I think that ‘ASO4AQH2O2J’ is calculated by the reaction ‘SO2+H2O2 --> ASO4AQH2O2J + H2O’. Is it right??? And this reaction is included in CMAQ source code???
I’m so appreciate for your replying.
I’ve just checked aqchem.F of my CMAQ source file, and finally I found it!
Your replying is so helpful for me and that is a answer that I want.
Once again, thank you for your replying
