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).

Chlorophyll concentration provides an estimate of the live phytoplankton biomass in the surface layer. It is also referred to as the amount of the green pigment chlorophyll. The chlorophyll anomaly is generated when today's chlorophyll concentration data is compared to the bi-monthly mean. A positive anomaly indicates new algal growth. Bi-monthly mean values are averages calculated over 61 days.
