Tropospheric Emissions: Monitoring of Pollution (TEMPO) is a NASA Earth Venture-Instrument (EVI) that measures North American pollution at a high resolution and on an hourly basis. It is a spectrometer with sensors capable of detecting ultraviolet and visible wavelengths of light maintaining a constant view of North America enabling it to provide daily data on ozone, nitrogen dioxide, and other elements in the atmosphere. TEMPO is attached to the side of geostationary orbit satellites that face the earth. TEMPO's light-collecting mirror scans a complete and constant east to west field of regard (FOR). TEMPO detectors measure reflected sunlight from the Earth's surface and atmosphere back. TEMPO "monitors air quality from Mexico to Canada" with "scientists from both Mexico and Canada sharing TEMPO activities taking place in their home countries".

NASA Earth Venture-Instrument (EVI)
TEMPO, which is a collaboration between NASA and the Smithsonian Astrophysical Observatory is NASA's first Earth Venture Instrument (EVI) mission. NASA Earth Venture-Instrument (EVI) is an element within the Earth System Science Pathfinder Program (ESSP) which is under NASA Science Mission Directorate's Earth Science Division's (SMD/ESD). EVI's are series of innovative "science-driven, competitively selected, low cost missions". The series of "venture class" mission activities were recommended in the 2007 publication Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond. "[I]nnovative research and application missions that might address any area of Earth science" are selected through frequent "openly-competed solicitations".

NASA Earth Ventures Instrument (EVI) missions include NASA Earth Venture (EVI)] missions are "small-sized competitively selected orbital missions and instrument missions of opportunity" and include NASA-ISRO Synthetic Aperture Radar (NISAR), Surface Water and Ocean Topography (SWOT), ICESat-2, SAGE III on ISS, Gravity Recovery and Climate Experiment Follow On (GRACE FO), Cyclone Global Navigation Satellite System (CYGNSS), ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS), and the 2014 Global Ecosystem Dynamics Investigation lidar GEDI.
