Paper Abstract

The World's first Ocean Color Observation Satellite, the GOCI (Geostationary Ocean Color Imager) equipped with is scheduled to be launched on Communication, Ocean and Meteorological Satellite (COMS) in November 2009. Korea Ocean Research & Development Institute (KORDI) has developed GOCI Data Processing System (GDPS) which produces ocean environment analysis data such as chlorophyll concentration, TSS, CDOM, Red-Tide, water current vector, etc. In order to retrieve water-leaving radiance more precisely, atmospheric and BRDF (Bi-Directional Reflectance Distribution Function) correction algorithms optimized for the environment of the GOCI coverage area and COMS satellite orbit characteristics have been developed and implemented into the GDPS. GOCI operational atmospheric correction algorithm has a capability to retrieve water-leaving radiance in the presence of aerosols with high optical thickness (i.e. Asian Dust). At-sensor radiance which is affected by relative change of the Sun and satellite position is corrected by the GOCI BRDF Correction algorithm. GOCI L2 data which is the product of the GDPS is provided with 8 VNIR band images with 4967 x 5185 pixel resolution on the GOCI coverage area. As GOCI main operation center, Korea Ocean Satellite Center (KOSC) has been established by KORDI. Main operational functions of KOSC are the acquisition, processing, and storage of the GOCI data and distribution service of ocean satellite standard products generated from the GOCI data. Operational systems of KOSC are GDAS(GOCI Data Acquisition System), IMPS(Image Pre-processing System), GDPS, DMS(Data Management System), and GDDS(GOCI Data Distribution System). After the launch, KOSC has a plan to provide the GOCI data for the real time ocean environment and marine bio-physical phenomena variability monitoring.
