What happened? What did you expect to happen?

https://github.com/geoschem/GCHP/blob/e499969f3831261e1fd15774b9fc68d01d012ba2/src/GCHP_GridComp/GCHPctmEnv_GridComp/GCHPctmEnv_GridCompMod.F90#L873-L885

Humidity is positive so 1-SPHU is smaller than 1, so dryMF = MF/(1-SPHU) is bigger than MF, which does not make sense to me. Shouldn't mass flux from GMAO archives be multiplied instead of being divided by 1-SPHU?

What are the steps to reproduce the bug?

Run a mass flux simulation with dry pressure advection.

Please attach any relevant configuration and log files.
