NASA Air Quality Missions
NASA has a fleet of Earth-observing satellites whose instruments observe our planet's oceans, biosphere, and atmosphere. Several of these satellites have instruments that observe air pollutants around the world. The data collected are used by air quality managers and researchers studying the impact of air pollution on human health and agriculture.
MAIA: The Multi-Angle Imager for Aerosols instrument (MAIA) is scheduled to launch in 2022. MAIA will study the effects of particulate matter on human health in both the short term and the long term, and will also collect data on naturally occurring and anthropogenic air quality events.
PACE: The Plankton, Aerosol, Cloud ocean Ecosystem (PACE) satellite, scheduled to launch in 2022, will continue NASA’s efforts to observe the Earth’s oceans. PACE will carry two primary instruments. The first, an ocean color instrument, will collect data on global ocean biology. The second, multi-angle polarimeters, will measure how sunlight changes as it passes through clouds, aerosols and the ocean, providing detailed information about the Earth’s atmosphere and oceans.
TEMPO: The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument is scheduled to launch in 2022. TEMPO will use a spectrometer to make hourly measurements of ozone, nitrogen dioxide and other air pollutants across North America.
