MODIS / Aqua NIR-SWIR Ocean Color Products

The MODIS/Aqua NIR-SWIR ocean color products are derived by using the shortwave infrared (SWIR)-based atmospheric correction algorithm developed by the NOAA/NESDIS Center for Satellite Applications and Research (STAR). The products include chlorophyll concentration, remote sensing reflectance at 667 nm, water attenuation coefficient at 490 nm over 12 CoastWatch Regions-of-Interest, i.e., Northeast (NE), Southeast (SE), Gulf of Mexico (GOM), Caribbean (CB), West Coast (WC), Alaska (AK), East Tropical Pacific (EP), Equatorial Atlantic (EA), Great Lakes (GL), Hawaii (HI), North Atlantic (NA), and Pacific Basin (PB).

Water attenuation coefficient (Kd490) defines the presence of light (downwelling irradiance) versus depth, the depth of euphotic zone, and ultimately the maximum depth of primary production.
