Development of Data Processing System for High Resolution Geostationary Ocean Color Satellite Data

Abstract

Ocean color satellite, which is mainly used for monitoring changes in ocean chlorophyll and marine environment, has expanded its application area for monitoring coastal fishery and cultivation, river discharge, evolving to provide more and more high-resolution data. Geostationary Ocean Color Imager&#8211 II (GOCI-II), the successor satellite sensor platform of GOCI, will be possible to observe turbidity change, sea surface current and the change inside the bay at 250 meter spatial resolution. In particular, the geostationary ocean color satellite has the advantage that can observe short-term ocean changes like suspended sediments diurnal variation by providing one-hour periodic images. To meet the increased of GOCI-II user requirement, GOCI-II Ground Segment(G2GS), which is new ground system for the production of real-time data such as GPU-based parallel processing and personalized cloud service, is constructing. The ocean color algorithm development environment (OCADE) is also developed to apply traditional and innovative data analysis techniques for production of various deliverable of GOCI-II. The 250 meter high resolution ocean color remote sensing data processed by this system is planned to be provided to marine and coastal researchers via the homepage and ftp server. We report the coastal application of GOCI/GOCI-II and the status of the ground segment system of GOCI-II with a foreseen launch in 2019.more high-resolution data.
