Abstract

The Geostationary Environmental Monitoring Spectrometer (GEMS) and the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instruments will provide a new capability for the understanding of air quality and pollution. Ball Aerospace is the developer of these UV/Vis Hyperspectral sensors. The GEMS and TEMPO instrument use proven remote sensing techniques and take advantage of a geostationary orbit to take hourly measurements of their respective geographical areas. The high spatial and temporal resolution of these instruments will allow for measurements of the complex diurnal cycle of pollution driven by the combination of photochemistry, chemical composition and the dynamic nature of the atmosphere. The GEMS instrument was built for the Korea Aerospace Research Institute and their customer, the National Institute of Environmental Research (NIER) and the Principle Investigator (PI) is Jhoon Kim of Yonsei University. The TEMPO instrument was built for NASA under the Earth Venture Instrument (EVI) Program. NASA Langley Research Center (LaRC) is the managing center and the PI is Kelly Chance of the Smithsonian Astrophysical Observatory (SAO).

Bibliographical note

Funding Information:
The GEMS instrument was built for the Korea Aerospace Research Institute (KARI) for KARI’s customer and end-user, the National Institute of Environmental Research (NIER) in the Republic of Korea. The GEMS science team is led by Prof. Jhoon Kim from Yonsei University, Seoul, Korea.

Funding Information:
The primary mission of the TEMPO missions is to make the first trace gas measurements of Earth’s atmosphere from geostationary orbit. TEMPO and GEMS addresses the trace gas and aerosol measurement objectives of the GEOstationary Coastal and Air Pollution Events (GEO-CAPE) mission4. The GEO-CAPE mission was recommended by the 2007 National Research Council (NRC) Earth Science Decadal Survey5. The TEMPO and GEMS missions also contribute to the Science and Applications Priorities listed in the 2017 Decadal Survey, Thriving on Our Changing Planet: A Decal Strategy for Earth Observation from Space6. The UV/Vis hyperspectral sensors will make measurements of trace gases critical to the understanding of ground level ozone and aerosol pollution. The baseline and measurement goals include NO2, O3, SO2, C2H2O2, CH2O and atmospheric aerosol. While these measurements have been made by multiple instruments in a low Earth orbit (LEO), the measurement from a geostationary orbit provides hourly measurements during daylight hours. This high temporal and spatial resolution is critical to observing and better understanding the complex and dynamic air pollution levels and chemistry.
