Introducing the Geostationary Ocean Color Imager
GOCI
GOCI, Geostationary Ocean Color Imager
GOCI is an oceanic payload among the three observers of the Communication, Ocean and Meteorological (COMS), the world's first geostationary orbit satellite.
The Korea Ocean Satellite Center of the Korea Institute of Ocean Science & Technology, which is a major organization of GOCI, provides marine environment information in real time by using the GOCI data.
