Abstract
After the successful launch and operation of Geostationary Ocean Color Imager (GOCI), the first pathfinder of ocean color remote sensing in geostationary orbit from 2010, is in nominal operation phase around six years since its launch in June 2010. Regarding the scheduled lifetime of 7.7 years, successive mission of GOCI with the new generation of instrument design is highly requested by the international ocean color remote sensing users as well as domestic users in Korea.Development project of GOCI-II has been started in 2012 and currently, the launch is planned in 2019. The mission and user requirements of GOCI-II are defined by Korea Institute of Ocean Science and Technology (KIOST) and international GOCI PI (Principal Investigators). As a second generation of FR (Filter Radiometer) type ocean color imager in geostationary orbit, GOCI-II, will be able to monitor the nearly full Earth disk area at the same orbital location of GOCI (128.2˚E longitude in geostationary orbit), and to acquire the local area(observation region can be freely definable by user) image with 250m GSD and 12 spectral bands from visible to NIR (370~885nm) and one additional panchromatic band (402~885nm). It means 4 times more number of pixels and 50% more spectral bands than GOCI (250m spatial resolution at nadir. These enhanced features will be enable to enhance the monitoring and research capability to the level of climate data recordne 2010.
