Geostationary Southern Hemisphere air pollution sensors for a global constellation (Conference Presentation)

With the launch of the Geostationary Environment Monitor Spectrometer (GEMS) in 2020, the Tropospheric Emissions: Monitoring of Pollution (TEMPO) in 2023, and the near-term launch of Sentinel 4, the Atmospheric Composition Virtual Constellation, as envisioned by the Committee on Earth Observation Satellites (CEOS), is on its way to being realized. The established atmospheric composition sensor designs, associated retrieval algorithms and the science around the data’s use offers an opportunity to extend the CEOS constellation to the Southern Hemisphere. BAE Systems, Inc. is in a unique position to offer build-to-print geostationary sensors for the Southern Hemisphere based on GEMS and TEMPO. An overview of the GEMS and TEMPO instrument capabilities and the extension of these instruments to the Southern Hemisphere will be presented.
