Abstract

GOCI-II, which is the successor of GOCI (Geostationary Ocean Color Imager), will generate huge datasets like GOCI-II Level 1B dataset (geometrically corrected radiance), GOCI-II Level 2 dataset (26 pre-defined products related to ocean color, optical properties, ocean phenomena observing, atmospheric monitoring, land change monitoring) in GOCI-II local area and full disk area by Ocean Data Processing Subsystem (ODPS) of GOCI-II Ground Segment (G2GS) in real-time mode or in delayed mode. Data Service Environment (DSE) of G2GS will provide all datasets via various services. In order to ensure usability, we have provided a data retrieval and user support environment using a standardized framework (SNAP). The DSE was applied to retrieve satellite data through the GOCI Library, to retrieve only necessary data in the required area, and to retrieve data from Lucene search engine and OPeNDAP / THREDDS. In addition, it is also possible to search for filename, date of creation and metadata in the NetCDF file format. We plan to complete the system implementation and integration test before launching the satellite and evaluate whether the operation requirements will be met by in-orbit test (IOT) after launching the satellite.r, optical properties, ocean phenomena observing, atmospheric monitoring, land change monitoring) in GOCI-II local area and full disk area by Ocean Data Processing Subsystem (ODPS) of GOCI-II Ground Segment (G2GS) in real-time mode or in delayed mode.
