Tropospheric Emissions: Monitoring of Pollution

Tropospheric Emissions: Monitoring of Pollution (TEMPO) is a space-based spectrometer designed to measure air pollution across greater North America at a high resolution and on an hourly basis. The <a href="/facts/Ultraviolet%E2%80%93visible_spectroscopy/MUPLLczo">ultraviolet–visible spectrometer</a> will provide hourly data on ozone, nitrogen dioxide, and formaldehyde in the atmosphere.
TEMPO is a hosted payload on a commercial <a href="/facts/Geostationary_communication_satellite/xWRv8lAL">geostationary communication satellite</a> with a constant view of North America. TEMPO's spectrometer measures reflected sunlight from the Earth's atmosphere and separates it into 2,000 component wavelengths. It will scan North America from the Pacific Ocean to the Atlantic Ocean and from the Alberta oil sands to Mexico City. TEMPO will form part of a geostationary constellation of pollution-monitoring assets, along with the planned <a href="/facts/Sentinel-4/tNckB9Vk">Sentinel-4</a> from <a href="/facts/European_Space_Agency/L8YRNV0C">ESA</a> and Geostationary Environment Monitoring Spectrometer (GEMS) from South Korea's <a href="/facts/Korea_Aerospace_Research_Institute/07560nHx">KARI</a>.
On 3 February 2020, <a href="/facts/Intelsat/uktuBLn9">Intelsat</a> announced that the <a href="/facts/Intelsat/uktuBLn9">Intelsat 40e</a> satellite will host TEMPO. <a href="/facts/Maxar_Technologies/ta0E2dJD">Maxar Technologies</a>, the builder of the satellite, is responsible for payload integration. The launch occurred on 7 April 2023.
