Description

This PR resolves issue #3888
This PR adds the capability to process analysis tracer fields into aerosol AOD product in GRIB2 format using the upp tool within the GCAFS workflow. The analysis fields are on the Gaussian grid and are generated by adding aerosol increments (aeroinc_gaussian) and atmospheric increments (atminc) to the atmf006 background file. This feature is integrated into the aeroanlfinal job.

A new GCAFS control file has been updated in UPP. The UPP hash should be updated in ufs model and fv3atm. This will be addressed by PR (waiting for review): NOAA-EMC/fv3atm#985
