CMAQ STM methods

Hi, all!

I have a question of running of CMAQ STM module.

I’m using the CMAQ v5.3.1 with STM option.
And I found that if initial and boundary condition files include STM values not zero, they could affect the whole STM values in CONC file.

So, should I initialize all of STM species values by ‘0’ in initial boundary condition file ??

And I also want to know where the source of ‘ASO4ICBC’ in CMAQ-STM is.

I wish I can get any responses from you.

Thank you.
