Monitoring Atmospheric Composition by Geo-Kompsat-2: Goci-2, Ami and Gems

Monitoring of aerosol optical properties in high temporal and spatial resolution has been realized with the launch of Geostationary Ocean Color Imager (GOCI) and Meteorological Imager (MI) onboard the Communication, Oceanography, and Meteorology Satellite (COMS), also known as GEO-KOMPSAT (GK)-1 in 2010. In 2018, Advanced MI (AMI) will be launched with further enhanced capability onboard the GK-2A. GOCI-2 onboard GK-2B is planned to be launched in late 2019-early 2020 with Geostationary Environment Monitoring Spectrometer (GEMS). GEMS is a UV-visible spectrometer to monitor column concentration of trace gas including O₃, NO₂, SO₂ and HCHO, for the first time in high temporal and spatial resolution. In this study, results and plan to monitor atmospheric composition from geostationary earth orbit(GEO) are presented.
