Abstract
Geostationary Ocean Color Imager(GOCI), as the world’s first sensor to observe the ocean in geostationary orbit, has been developed with eight VIS/NIR bands, two mega pixel CMOS detector array. The GOCI has acquired 16 slot images in 2,500km x 2,500km area centered at 36˚ N and 130˚ E during 30 minutes. GOCI Level 1B data, that is total radiance detected by GOCI and processed by Image Pre-processing System(IMPS), should beapplied to derive ocean analysis products as GOCI Level 2 by GOCI Data Processing System(GDPS) in eight times per day. GDPS has the atmospheric correction algorithms and several Case-II underwater algorithms. Also, GDPS has the functionality to generate the value added products and the daily composite and the animation of time-series data.During in-orbit test period, GDPS will be verified with respect to the requirements, its interface, functionality and accuracy of outputs by pre-defined test procedure. And those configuration parameters will be tuned for correct processing of ocean color data. All processing of GDPS is performed automatically within 30 minutes after GOCI Level 1B injection. Its outputs are moved and registered immediately to Data Management System(DMS) in KOSC.For GOCI atmospheric correction algorithms, the output water leaving radiance(Lw) is compared with the existed polar-orbit ocean color satellite’s one. The demonstration of each algorithm will be shown its input/output data analysis results. The study of various candidate of standard algorithm will be performed by comparison with in-situ data.
