Data Description
Ocean Color SeaWIFS Products -
NOAA CoastWatch produces near real-time ocean color products, e.g. chlorophyll-a concentration and turbidity (reflectance), with data from NASA's GeoEye's Orbview-2 satellite (via contractual purchase). The data is collected by selected HRPT ground stations.The level 1A
data consists of raw radiance counts from eight bands (six in visible and two in near infrared spectrum), calibration data, navigation data, instrument telemetry and selected spacecraft telemetry. Each level 2 satellite specific product has unique characteristics dependent on the sensor
and the algorithm applied. While level 2 historic data is open to the public, level 1 data is restricted to users covered by SeaWIFS CoastWatch contract due to limitations associated with commercial data. Users may find instructions on how to become registered users with SeaWIFS at
