Abstract
GOCI-II (Geostationary Ocean Color Imager-II) is the next generation of GOCI, which was the first ocean color imager in the world operating on the geostationary orbit. GOCI has been monitoring ocean color around the Korean Peninsula in order to detect, monitor, quantify, and predict short term changes of coastal ocean environment for marine science research and application purpose. GOCI-II has improved radiometric and geometric performance in comparison with GOCI. GOCI-II is a multi-spectral imaging radiometer in order to observe ocean color around the Korean peninsula and to cover full earth disc even if the platform does not provide a pitch/roll tilt. It acquires data in 12 VNIR spectral bands (370~885nm) with a spatial resolution of about 250m GSD(Ground Sampling Distance) at nadir. GOCI-II will be operated at the same orbital position (128.2˚E Longitude in geostationary orbit) with GOCI.
GOCI-II mission operation mode consists of Global (Full Disk) mode, Local mode, Star imaging, Moon imaging, and Solar Calibration. Global mode is new capability of GOCI-II for global monitoring and research on the long-term climate change. Observation area of the global mode is a circle field of ±60° longitude and latitude central to the spacecraft nadir. Full disk will be accumulated a image during 1 day. GOCI-II also operated in user-definable LA mode. The user of GOCI-II can select the observation local area within the fur to detect, monitor, quantify, and predict short term changes of coastal ocean environment for marine science research and application purpose.
