chgres_cube: Problem using grib2 data with Thompson aerosol generation #180

Closed LarissaReames-NOAA closed 1 year ago

LarissaReames-NOAA commented 3 years ago

With grib2 input data, text in the variable mapping files is used to generate tracer arrays. When the GSD (i.e., Thompson) file is used, it creates arrays for liq_aero and ice_aero when all other tracer arrays are created, and then they're filled with data from the input file (e.g., HRRR) or a fill value. However, if the user wishes to use this same variable mapping file, but also wishes to generate aerosols using the new Thompson generation code (e.g., with GFS grib2 data which doesn't have these arrays), the Thompson code attempt to generate these arrays again which would cause the model to crash. The solutions, as I see them, are to either write in a check in the aerosol generation code that checks to see if the fields have already been created in ESMF, or create a new variable mapping file that includes entries for all Thompson tracers except the aerosols.

@LarissaReames-NOAA What is the status of this issue?

LarissaReames-NOAA commented 1 year ago

These aerosol arrays are not handled internally in the weather model, so this is no longer a relevant issue. Closing.
