GEOMETRIC PERFORMANCE ESTIMATION OF GEOSTATIONARY OCEAN COLOR IMAGER (GOCI) L1B DATA

Abstract

For a stable distribution service of GOCI data, various systems were installed as follows: GDAS, IMPS, GDPS, DMS, and GDDS. GOCI Data Acquisition System (GDAS) receives the GOCI raw data from satellite with L-band. Image Pre-Processing System (IMPS) produces Level 0, Level 1A, Level 1B data from GOCI raw data. GOCI Data Processing System (GDPS) produces Level 2 and LRIT, Radiometric Calibration Gain Matrix from IMPS output data. Data Management System (DMS) manages unified data archive in KOSC. Total Monitoring Control System (TMC) monitors the status of all systems in KOSC. GOCI Data Distribution System (GDDS) distributes GOCI data to users through EDES and KOSC website. External Data Exchange System (EDES) is developed for the data exchange among KORDI, KARI, KMA for the purpose of LRIT distribution and sharing GOCI browser image.
