Introduction to GEMS onboard GK-2B
Introduction
In order to enhance the capability of monitoring and predicting air quality and climate change over East and Southeast Asia, the National Institute of Environmental Research (NIER) under the Ministry of Environment, Korea developed the Geostationary Environment Monitoring Spectrometer (GEMS)
GEMS was launched in February 2020 onboard the GEO-COMPSAT-2B satellite 1
The UV-Visible hyper spectrometer measures atmospheric composition and climate forcers including sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3) formaldehyde (HCHO), and aerosols
GEO-KOMPSAT2B : The GK2B program was jointly promoted by three ministries (Ministry of Science, ICT and Future Planning, Ministry of Environment, and Ministry of Maritime Affairs and Fisheries)
Implications of the GEMS development
pioneering role
The world’s first geostationary air quality mission
Securing global leadership
A stepping stone to become a global leader In climate and atmospheric research
improvement of national prestige
Transformation from a satellite data recipient to a provider by producing and sharing GEMS data over East and Southeast Asia
A pivotal role in environmental monitoring
Playing a major role in global air quality monitoring as part of the GEO air quality constellation with the U.S. and Europe
