[RegCNET] About the vertical concentration distribution of aerosol?

[Zakey Ashraf_Saber]

Dear Su,
   The vertical mixing ratio is exist in the output and simply you can
convert it to mass concentration. The variable is called tracer mixing
ratio and it is in kg/kg in CHEM* files



With my best wishes,
Ashraf
