TEMPO data is archived and distributed freely through the Atmospheric Science Data Center. \u201cThe TEMPO mission has set a groundbreaking record as the first mission to surpass two petabytes, or 2 million gigabytes, of data downloads within a single year,\u201d said Mahmoud. \u201cWith over 800 unique users, the substantial demand for TEMPO\u2019s data underscores its critical role and the immense value it provides to the scientific community and beyond.\u201d Air quality forecasters, atmospheric scientists, and health researchers make up the bulk of the data users so far.<\/p>\n
The TEMPO mission is a collaboration between NASA and the Smithsonian Astrophysical Observatory, whose Center for Astrophysics Harvard & Smithsonian\u00a0oversees daily operations of the TEMPO instrument and produces data products through its Instrument Operations Center.<\/p>\n
Datasets from TEMPO will be expanded through collaborations with partner agencies like the National Oceanic and Atmospheric Administration (NOAA), which is deriving aerosol products that can distinguish between smoke and dust particles and offer insights into their altitude and concentration.<\/p>\n
\u201cThese datasets are being used to inform the public of rush-hour pollution, air quality alerts, and the movement of smoke from forest fires,\u201d said Xiong Liu, TEMPO\u2019s principal investigator at the Center for Astrophysics Harvard & Smithsonian. \u201cThe library will soon grow with the important addition of aerosol products. Users will be able to use these expanded TEMPO products for air quality monitoring, improving forecast models, deriving pollutant amounts in emissions and many other science applications.\u201d<\/p>\n
\u201cThe TEMPO data validation has truly been a community effort with over 20 agencies at the federal and international level, as well as a community of over 200 scientists at research and academic institutions,\u201d Judd added. \u201cI look forward to seeing how TEMPO data will help close knowledge gaps about the timing, sources, and evolution of air pollution from this unprecedented space-based view.\u201d<\/p>\n
An agency review will take place in the fall to assess TEMPO\u2019s achievements and extended mission goals and identify lessons learned that can be applied to future missions.<\/p>\n
The TEMPO mission is part of NASA\u2019s Earth Venture Instrument program, which includes small, targeted science investigations designed to complement NASA\u2019s larger research missions. The instrument also forms part of a virtual constellation of air quality monitors for the Northern Hemisphere which includes South Korea\u2019s Geostationary Environment Monitoring Spectrometer and ESA\u2019s (European Space Agency) Sentinel-4 satellite. TEMPO was built by BAE Systems Inc., Space & Mission Systems (formerly Ball Aerospace). It flies onboard the Intelsat 40e satellite built by Maxar Technologies. The TEMPO Instrument Operations Center and the Science Data Processing Center are operated by the Smithsonian Astrophysical Observatory, part of the Center for Astrophysics | Harvard & Smithsonian in Cambridge.<\/p>\n
