Hello.
I am curious if CMAQ-ISAM can tag for particle numbers.
In the isam_control.txt file,
I can choose only 9 options.
e.g. !!! Choose any/all from the list of nine: SULFATE, NITRATE, AMMONIUM, EC, OC, VOC, PM25_IONS, OZONE, CHLORINE
Should I change SA_DEFN.F to tag a new variable?
Best regards,
