GOCI-II 지상국의 시스템운영 및 자료서비스

Abstract

Geostationary ocean color imager-II (GOCI-II), the Korean second ocean color sensor in geostationary satellite, will be planned to launch in 2019. GOCI-II ground segment (G2GS) is under development as a new ground segment system for the GOCI-II. G2GS provides system operation environment (SOE) and data service environment (DSE) intend for system operators and data users. SOE should generate ocean color products automatically just after receiving GOCI-II sensor data. It has external interfaces for GOCI-II operation, telemetry and re-distribution by satellite. All information generated by G2GS SOE like GOCI-II Level 1B and GOCI-II Level 2 data is stored and distributed to data users by DSE. GOCI-II data will be uploaded as a slot-level NetCDF4 files on DSE storage. When users define those regions of interest, DSE will make new download links for each ROI. Also, GOCI toolbox (GTBX), which is GOCI-II data analysis tool like GOCI data processing system (GDPS) for GOCI, will be distributed as a plug-in program on SNAP framework. GTBX can access GOCI-II data in DSE data repository. Though GOCI-II data policy is not established yet, GOCI-II data will be available few day after data receiving with free of charge for public research purposes if we follow GOCI data policy. After in-orbit test of GOCI, we believe that we will provide various comfortable data services through GOCI-II DSE.
