About Tropospheric Emissions Monitoring of Pollution:
- It will monitor major air pollutants across North America.
- Observations:
- It will make important scientific observations, including that of ozone, nitrogen oxide, sulphur dioxide and formaldehyde levels.
- It is capable of measuring air quality over North America hourly during the daytime with a resolution of several square miles.
- It monitors the effects of everything from rush-hour traffic to pollution from forest fires and volcanoes.
- The present pollution-monitoring satellites are in low Earth orbit (LEO), but this new monitoring instrument is hosted in geostationary orbit.
- After this launch NASA has joined South Korea’s Geostationary Environment Monitoring Spectrometer and the European Space Agency’s Sentinel-4 satellite to become an air quality monitoring satellite constellation.
