Abstract :
Korea Aerospace Research Institute (KARI) has a plan to launch COMS for consistent monitoring of the Korean Peninsula. Korea Geostationary Ocean Color Imager (KGOCI) is one of the main payloads of COMS which will provide a monitoring of ocean-colour around the Korean Peninsula from geostationary platforms. Ocean color observation from geostationary platform is required to remedy the coverage constraints imposed by polar orbiting platforms. In this paper the main characteristics of KGOCI are described. It will provide the measurement data of 6 visible channels and 2 near-infrared channels (400 nm-900 nm). The high radiometric sensitivity is essential of ocean color sensor because of the weak water leaving radiance. The integration time and aperture diameter required to achieve the SNR specification of KGOCI are analyzed.
