The instrument also forms part of a virtual constellation of air pollution monitors for the Northern Hemisphere which also includes South Korea’s Geostationary Environment Monitoring Spectrometer and ESA’s (European Space Agency) Sentinel-4 satellite.

NASA has made new data available that can provide air pollution observations at unprecedented resolutions – down to the scale of individual neighborhoods. The near real-time data comes from the agency’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) instrument, which launched last year to improve life on Earth by revolutionizing ...
Using new, high-resolution global satellite maps of air quality indicators, NASA scientists tracked air pollution trends over the last decade in various regions and 195 cities around the globe. The findings were presented Monday at the American Geophysical Union meeting in San Francisco and published in the Journal of Geophysical Research.
The aircraft carry instruments that will collect data on a range of greenhouse gases including carbon dioxide and methane, as well as air pollutants such as nitrogen dioxide, formaldehyde, and ozone. One purpose of this campaign is to validate space-based measurements observed by the TEMPO (Tropospheric Emissions: Monitoring of Pollution ...
Early in the pandemic, it was expected that satellite imagery around the world would show cleaner air as a result of COVID-19 lockdowns. But not all pollutants were taken out of circulation. For tiny airborne-particle pollution, known as PM 2.5, researchers using NASA data found that variability from meteorology obscured the lockdown signals ...
“Together we can get a 3-D perspective of air pollution moving and mixing in different layers of air,” said Sullivan, project scientist of the Tropospheric Ozone Lidar Network , a high-powered network of lasers used to identify and locate pollutants. For example, during a STAQS deployment to New York, the ground teams collaborated to track ...
Harmful air pollution affects people and the environment and according to the World Health Organization, air pollution is responsible for about 7 million deaths worldwide each year. “The World Bank has estimated that the global cost of health damages from air pollution is $8.1 trillion , with people in low- and middle-income countries most ...
Clean air is essential for healthy living, but according to the World Health Organization (WHO), almost 99% of the global population breathes air exceeding their guideline limits of air pollution. “Air quality is a measure of how much stuff is in the air, which includes particulates and gaseous pollutants,” said Kristina Pistone, a research ...
Nitrogen dioxide is an air pollutant that is primarily produced by the combustion of fossil fuels used by industry and transportation—both of which were significantly reduced during the height of the pandemic to prevent the novel coronavirus from spreading.
Rebranded as Canary-S (Solar), the sensor is now meeting a need for low-cost, wireless air-quality and meteorological monitoring on Earth. The self-contained unit, powered by solar energy and a battery, transmits data using cellular technology.
