In the TEMPO Microphysics, the hygroscopic aerosol is referred as a “water friendly” aerosol (WFA), and the non-hygroscopic ice-nucleating aerosol is referred as “ice friendly” aerosol (IFA). For usual TEMPO applications, WFA and IFA are derived using GOCART climatologies. The default WFA emission is an empirical formula from the surface layer WFA, and no IFA emissions. In this PR, the sea-salt emission, organic carbon from wildfire biomass burning and anthropogenic emissions are combined to represent the WFA emission, while the prognostic emission of dust is used to represent IFA emission.

There is a namelist option of "config_mp_aero_emission" in the chemistry namelist file. It is false by default, and no impact on nwfa2d and nifa2d. If it is true, it will overwrite the nwfa2d and nifa2d every timestep.

This PR has been synced with the latest ufs-community:noaa/develop.

This is the same the ufs-community#240 to ufs-community/MPAS-Model repository.

    • no, the dust input file will be updated in the rrfs-workflow.
  • Does this PR require updating one or more baselines for the CI tests? If so, what?
    • no
