Overview of Geostationary Ocean Color Imager (GOCI) data distribution service

Abstract

The Korea Ocean Satellite Center (KOSC) of Korea Institute of Ocean Science & Technology (KIOST) is the main operating institutue of the Geostationary Ocean Color Imager (GOCI) which was launched in 2010. The distribution of GOCI data was started in April, 2011. Since then the KOSC provides radiometric/geometric calibrated (Level-1B) data and ocean products (Level-2) data to public users through our web site and off line. Recently, demand for the operational application of GOCI data explosively increased. Therefore, the concept of operation for GOCI data service was changed from support the research to operational application service. Using the FTP service, the KOSC effectively support the related organizations by providing services for the operational application of GOCI on various national issues such as red tide, green tide, brown algae, low salinity water, sea fog, sea ice, coastal upwelling, and so on. These efforts are stretched even to the application on land/atmospheric phenomena such as typhoon, forest fire, aerosol, and so on. The service has helped the many local governments to mitigate the damage from various phenomena. As a result, the number of GOCI data download was increased rapidly from 70,000 (2014~2015) to 1,000,000 (2016~2018) per year. The number of related organizations increased to 33. There is a continuing request from the unincluded organizations.
