Description

There are some minor differences between JRA55 and JRA55do. In JRA55do, rain and snow are provided as seperate variables. In the current datamode they are the same variable and it's assumed to be snow if air temp is below the freezing temperature:

I'll make a PR to support seperate streams for the snow and rain variables (and keep current behavior)

Research direction

Start by reading datm/datm_datamode_jra_mod.F90 around lines 276-282 and compare the current JRA55 precipitation handling with the JRA55do distinction described in the issue. Done means DATM supports separate JRA55do rain and snow streams while preserving the existing behavior for JRA55.
