GEMS

Geostationary Environment Monitoring Spectrometer 

Early warnings 

Our GEMS instrument will help to improve early warnings for dangerous pollution events across the Asia-Pacific region and also monitor long-term climate change. 

A geostationary scanning ultraviolet-visible spectrometer, GEMS will monitor trans-boundary pollution events for the Korean peninsula and Asia-Pacific region. Our instrument provides high spatial and temporal resolution hourly measurements of ozone, its precursors and aerosols.

GEMS will fly on the GEO-KOMPSAT-2B geostationary satellite in a scheduled 2018 launch.

What we’re doing

Instrument provider

We’re building GEMS under a commercial contract with the Korea Aerospace Research Institute (KARI) for the National Institute of Environmental Research in the Ministry of Environment of South Korea. Together, Ball and KARI engineers will design, fabricate and test the GEMS instrument. 

GEMS is the Asian element of a global air quality monitoring constellation of geostationary satellites that includes the Tropospheric Emissions: Monitoring of Pollution (TEMPO) spectrometer. We’re building TEMPO for NASA Langley Research Center and Harvard Smithsonian Astrophysical Observatory. Both GEMS and TEMPO leverage our know-how and the tech we’ve developed for earlier ultraviolet-visible instruments.
