Hello everyone, I'm presently using the CAMS global forecast compostion to update the boundary conditions of gaseous species in WRF-Chem using MOZBC utility, and found it to be very useful. But I also want to update the aerosol species from CAMS. I'm using the GOCART option to simulate dust storm episodes. Is there a mapping to convert the aerosol species from CAMS aerosol module to GOCART aerosol schemes? Here is the list of aerosol species available from CAMS. | Param | Short name | Long name | | 1.210 | aermr01 | Sea Salt Aerosol (0.03 - 0.5 um) Mixing Ratio | | 2.210 | aermr02 | Sea Salt Aerosol (0.5 - 5 um) Mixing Ratio | | 3.210 | aermr03 | Sea Salt Aerosol (5 - 20 um) Mixing Ratio | | 4.210 | aermr04 | Dust Aerosol (0.03 - 0.55 um) Mixing Ratio | | 5.210 | aermr05 | Dust Aerosol (0.55 - 0.9 um) Mixing Ratio | | 6.210 | aermr06 | Dust Aerosol (0.9 - 20 um) Mixing Ratio | | 7.210 | aermr07 | Hydrophobic Organic Matter Aerosol Mixing Ratio | | 8.210 | aermr08 | Hydrophilic Organic Matter Aerosol Mixing Ratio | | 9.210 | aermr09 | Hydrophobic Black Carbon Aerosol Mixing Ratio | | 10.210 | aermr10 | Hydrophilic Black Carbon Aerosol Mixing Ratio | | 11.210 | aermr11 | Sulphate Aerosol Mixing Ratio | Thank you very much, Best regards, Maria
