Where Does NASA fit?
NASA instruments — on satellites, planes, and the ground — constantly collect data on air quality. NASA-funded scientists track the sources and concentrations of major pollutants and their movement through the atmosphere. They provide managers and policymakers with Earth observations that can inform decisions around air quality for economic and human benefit.

NASA Mission: TEMPO
TEMPO, or Tropospheric Emissions: Monitoring of Pollution, is the first space-based instrument to continuously measure air quality above North America with the resolution of a few square miles. It is a collaboration between NASA and the Harvard-Smithsonian Astrophysical Observatory.

NASA Mission: PACE
The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission helps us understand our ocean and atmosphere by measuring key variables associated with cloud formation, particles and pollutants in the air, and microscopic, floating marine life (phytoplankton). These observations provide us better monitors of ocean health, air quality, and climate change.

Human Fingerprint on Global Air Quality
Scientist Bryan Duncan and his team examined observations made from 2005 to 2014 by the Ozone Monitoring Instrument aboard NASA’s Aura satellite. One of the atmospheric gases the instrument detects is nitrogen dioxide, a yellow-brown gas that is a common emission from cars, power plants, and industrial activity.
Nitrogen dioxide can quickly transform into ground-level ozone, a major respiratory pollutant in urban smog. Nitrogen dioxide hotspots, used as an indicator of general air quality, occur over most major cities in developed and developing nations.

NASA and NOAA Take to the Air to Chase Smoke
NASA, NOAA and university partners are taking to the skies, and the ground, to chase smoke from fires burning across the United States.
The Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) is starting in Boise, Idaho, with a long-term of goal of improving our understanding of how smoke from fires affects air quality across North America.
