Short Name:

COMS Geostationary Ocean Color Imager (GOCI) Ocean Color (OC) Regional Data

The Geostationary Ocean Color Imager (GOCI) is one of the three payloads onboard the Communication,Ocean and Meteorological Satellite (COMS). It acquires data in 8 spectral bands (6 visible, 2 NIR) witha spatial resolution of about 500m over the Korean sea. The ocean data products that can be derivedfrom the measurements are mainly the chlorophyll concentration, the optical diffuse attenuationcoefficients, the concentration of dissolved organic material or yellow substance, and the concentrationof suspended particles in the near-surface zone of the sea. In operational oceanography, satellite deriveddata products are used in conjunction with numerical models and in situ measurements to provide forecastingand now casting of the ocean state. Such information is of genuine interest for many categories of users.
