What new functionality do you need?

The current GCAFS doesn't generate the aerosol AOD analysis products in grib2 format. The AOD analysis needs to be processed from aerosol tracer fields using UPP. This job will be implemented within the atmanlupp task .

Acceptance Criteria

• aero analysis tasks and atmanlupp task complete successfully
• File {COMROOT}/model/atmos/master/gcdas.txxz.master.analysis.grib2 with anl AOTK variables produced
• File {COMROOT}/analysis/chem/gcdas.txxz.analysis.aero.a006.nc produced

Suggest a solution (optional)

Implement this feature within the atmanlupp task.

1. Stage the Gaussian atmos analysis file and surface file in aeroanlinit task.
2. Get Gaussian aerosol analysis by adding the aerosol background and increments, which could be performed in the aeroanlfinal task.
3. Process aerosol analysis to grib2 format in atmanlupp task using a new upp configuration file for GCAFS/GCDAS: upp_gcafs.yaml
