Abstract

The Geostationary Environment Monitoring Spectrometer (GEMS) on the GEO-KOMPSAT 2B satellite is the first UV-visible instrument on geostationary platforms for providing optical, chemical, and physical properties of aerosols and atmospheric gases including nitrogen dioxide, sulfur dioxide, ozone, and formaldehyde. The National Institute of Environmental Research (NIER) of the Korean Ministry of Environment operates GEMS and produces, applies, and distributes GEMS data. NIER obtains data from GEMS observations and provides air quality information in temporal resolution of one hour and spatial resolution of 3.5 km × 8 km for most products over Asia. This presentation focuses on air quality studies using GEMS data, which analyze variations in aerosol and gaseous species concentrations over the recent years. The use of GEMS for monitoring exceptional events such as volcanoes and forest fires is also addressed. Additionally, results of applying GEMS Aerosol Optical Depth (AOD) were discussed to calculate aerosol motion vectors and assimilate with Chemistry Transport Model (CTM) data. This presentation highlights the potential of GEMS data for improving air quality monitoring and forecasting.
