The Geostationary Ocean Color Imager (GOCI) was one of the three payloads onboard the Communication, Ocean and Meteorological Satellite (COMS) operated by the Korean Meteorological Association (KMA), Astrium, Korean Aerospace Research Institute (KARI), and Korean Institute of Ocean Science and Technology (KIOST). GOCI acquired data in eight spectral bands (six visible, two near-infrared) with a spatial resolution of approximately 500 meters over the Korean sea. 

The ocean data products that can be derived from the measurements are mainly the chlorophyll concentration, the optical diffuse attenuation coefficients, the concentration of dissolved organic material or yellow substance, and the concentration of suspended particles in the near-surface zone of the sea. In operational oceanography, these satellite derived data products are used in conjunction with numerical models and in situ measurements to provide forecasting and now casting of the ocean state.
