The designated archive for NASA ocean color data is the Ocean Color Web, maintained by the NASA Ocean Biology Processing Group (OBPG). Data products from the Coastal Zone Color Scanner (CZCS), the Ocean Color and Temperature Scanner (OCTS), the Sea-Viewing Wide Field-of-view Sensor (SeaWiFS), and the Moderate Resolution Imaging Spectroradiometer (MODIS) are contained in this archive.
MODIS-Terra and MODIS-Aqua data includes very accurate sea surface temperature (SST) data. SST is a fundamental variable that researchers use to observe and understand the constantly changing patterns of circulation in the world's oceans. The interaction between currents and living organisms creates the multiple intertwined patterns of chlorophyll that are perceived by Ocean Color sensors.
The NASA GES DISC, which was the former archive for CZCS, SeaWiFS, MODIS-Aqua, and OCTS data, now provides ocean color data in Level 3 global gridded format (Standard Mapped Image) in the Giovanni visualization and analysis system.
