NASA's new satellite TEMPO measures air pollution hourly has shown significant progress and now the space agency officials are already thinking about ways to extend its life.

About TEMPO satellite 

  • Tropospheric Emissions Monitoring of Pollution (TEMPO) monitors major air pollutants across North America.
  • Its monitoring range extends from Canada’s oil sands to the Yucatán Peninsula and across the Atlantic to the Pacific Ocean.
  • It is part of a virtual constellation with South Korea's Geostationary Environment Monitoring Spectrometer (GEMS) and the European Space Agency’s upcoming satellite, aiming for comprehensive air pollution monitoring over the Northern Hemisphere.
  • 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.
  • It was designed for a 20-month operation.

Q1) What is Ozone?

Ozone is an odorless, colorless gas made up of three oxygen molecules (O3) and is a natural part of the environment. It occurs both in the Earth’s upper atmosphere, or stratosphere, and at ground level in the lower atmosphere, or troposphere.
