Researchers and environmental scientists have gained an unprecedented tool in the fight against air pollution over North America with the deployment of a new satellite. Launched last year, the satellite, named TEMPO (Tropospheric Emissions: Monitoring of Pollution), is a game-changer in tracking air quality on an hourly basis.
Offering daylight measurements with unparalleled precision, TEMPO orbits 22,000 miles above the Earth’s equator. It commenced operations by taking its inaugural readings on July 31, revealing concerning levels of nitrogen dioxide over major cities such as Washington, D.C., and Los Angeles. These concentrations showed notable variation within a matter of hours, indicating the dynamic nature of air pollution.
Unlike previous monitoring tools that could only capture larger swaths of land, TEMPO zooms in to provide data on areas as small as four square miles. It also has the capability to measure ozone levels from the surface to 1.25 miles in altitude. This advancement comes with the promise of significantly enhancing our understanding of pollution sources and movements, as well as offering insights into daily pollution patterns.
The enhanced resolution and frequency of data collection could lead to the development of mobile applications offering real-time pollution updates. Such technology would be particularly beneficial for vulnerable populations and could facilitate timely public health warnings about air quality.
NASA’s Langley Research Center manages the TEMPO project, underscoring the collaboration between NASA and the Smithsonian Astrophysical Observatory. Research studies are already underway, leveraging TEMPO’s rich dataset to push forward the scientific understanding of atmospheric pollution.

FAQs about TEMPO Satellite and Air Pollution Monitoring
What is the TEMPO satellite?
TEMPO (Tropospheric Emissions: Monitoring of Pollution) is a new satellite launched to monitor air pollution over North America. It provides precision measurements of air quality at an hourly rate during daylight.
What makes TEMPO different from previous monitoring tools?
TEMPO offers unparalleled precision and focuses on much smaller geographic areas as small as four square miles. It can also measure ozone levels from the surface up to an altitude of 1.25 miles. TEMPO delivers data with higher resolution and frequency than previous satellites.
What kind of pollutants can TEMPO monitor?
TEMPO is equipped to measure levels of nitrogen dioxide and ozone.
Why is it important to monitor the air pollution levels?
Air pollution is dynamic, with levels changing within hours. Monitoring allows us to understand the sources and movements of pollution, assess public health risks, and develop strategies to mitigate these risks.
How might the general public benefit from TEMPO’s data?
The detailed and frequent data from TEMPO could lead to the development of mobile apps providing real-time pollution updates. This can help individuals, especially those vulnerable to poor air quality, by offering timely public health warnings.
Who manages the TEMPO project?
NASA’s Langley Research Center manages the project in collaboration with the Smithsonian Astrophysical Observatory.
Can I learn more about emerging clean technologies?

– Nitrogen dioxide (NO2): A toxic gas that can contribute to pollution and has adverse effects on human health.
– Ozone: A molecule composed of three oxygen atoms, ozone high in the atmosphere protects us from ultraviolet sunlight, but at ground level, it is a harmful air pollutant.
– Atmospheric pollution: The presence of substances in the atmosphere that are harmful to human health or the environment.
