CMAQ
1

Hi everyone,
I know how to obtain the PH value in cloud water according toEstimation of pH value in the cloud water using CCTM or MCIP species

I would like to know whether I can estimate the PH value of rain based on CMAQ.

Thanks,
Lingyun

An estimate for the rain pH may be obtained using the HPLUS variable in the wet deposition (CCTM_WETDEP1 or CCTM_WETDEP2) files + precipitation.
