Data Description

OBPG SeaWiFS Monthly Global 9-km Products

The products available for analysis are SeaWiFS Standard Mapped Image (SMI) products. Three of these products are ocean products: chlorophyll a concentration, diffuse attenuation coefficent at 490 nm, and normalized water-leaving radiance at 555 nm. Two of the products are atmospheric products: Angstrom coefficient 510 to 865 nm, and aerosol optical thickness at 865 nm.

OBPG MODIS/Aqua Monthly Global 9-km Products

The data products available for analysis are 9-km spatial resolution MODIS Aqua monthly SMI (Standard Mapped Image) products from the Ocean Biology Processing Group (OBPG). These data products are generated with data processing methods similar to those applied to SeaWiFS and are not the same as the standard MODIS Aqua products archived by the GES DISC DAAC (see http://oceancolor.gsfc.nasa.gov/ for more information). Four of these products are ocean products: chlorophyll a concentration, diffuse attenuation coefficent at 490 nm, normalized water-leaving radiance at 551 nm, and sea surface temperature. Two of the products are atmospheric products: Angstrom coefficient 531-869 nm, and aerosol optical thickness at 869 nm.
