MERRA-2 FAQ: What are the wavelength-dependent optical properties for aerosol species across various wavelengths?
Posted: Fri Dec 05, 2025 9:37 pm America/New_York
The document Supplemental Documentation for GEOS Aerosol Products (https://gmao.gsfc.nasa.gov/pubs/docs/Collow1489.pdf) discusses MERRA-2 aerosol formulation through the more recent systems. Section 4 discusses the optical properties, and a NetCDF File (https://portal.nccs.nasa.gov/datashare/iesa/aerosol/AerosolOptics/) provides the values of the aerosol optical properties.
