GEMS On Orbit: An Instrument for Air Pollution Sensing of East Asia from Geostationary Orbit
Abstract
The Geostationary Environmental Monitoring System (GEMS) provides a new capability for understanding the formation, evolution and distribution of air pollution. Ball Aerospace, working with the Korea Aerospace Research Institute (KARI) and their customer the National Institute of Environmental Research (NIER), built and tested the GEMS sensor that now sits in geostationary orbit over the West Pacific. GEMS measures spectral radiances in the UV-Vis at high spatial and temporal resolution. The measurements are used with atmospheric retrieval techniques to resolve the complex diurnal cycle of pollution driven by photochemistry, chemical composition and the dynamic nature of the atmosphere. Final ground tests, launch and on-orbit activation and testing will be presented.
