Abstract:
One of the key components of NASAs Earth Science Research Strategy to better understand the complex nature of Earths climate is the determination of the global radiation balance. Comprehensive regional-to-global climate models (R/GCM) are playing an ever-greater role in addressing this issue. Because of their important role in modifying the radiative energy balance, the characteristics of aerosols, especially near their sources and sinks, are essential parameters to the R/GCMs. Many EOS era instruments (e.g., SeaWiFS, MODIS, MISR, etc.) are designed to provide such information with a high degree of fidelity. A README can be found at ftp://measures.gsfc.nasa.gov/data/s4pa/DeepBlueSeaWiFS_Level3/SWDB_L3M10.003/doc/README.DeepBlueSeaWiFS.pdf Parameters contained in the data files include the following: aerosol_optical_thickness_550_land | aerosol optical thickness estimated at 550 nm over land | (1) aerosol_optical_thickness_550_land_ocean | aerosol optical thickness estimated at 550 nm over land and ocean | (1) aerosol_optical_thickness_550_ocean | aerosol optical thickness estimated at 550 nm over ocean | (1) aerosol_optical_thickness_land | aerosol optical thickness at 412 nm, 490 nm, and 670 nm over land | (1) aerosol_optical_thickness_ocean | aerosol optical thickness at 412 nm, 490 nm, and 670 nm over ocean | (1) angstrom_exponent_land | angstrom exponent over land as derived from aerosol optical thickness at 412 nm and 490 nm | (1) angstrom_exponent_land_ocean | angstrom exponent over land and ocean as derived from aerosol optical thickness at 412 nm and 490 nm | (1) angstrom_exponent_ocean | angstrom exponent over ocean as derived from aerosol optical thickness at 412 nm and 490 nm | (1) End of parameter information |
