MOPITT Helps Shape the Future of Air Quality Monitoring
Measurements of Pollution in the Troposphere (MOPITT) on NASA’s Terra satellite is being used to prove a concept in which new geostationary satellites could improve how agencies monitor and forecast air quality. Chemistry-climate model output would be combined from satellite data from a fleet of geostationary satellites.
"We think the new perspective made possible by geostationary sensors would provide data that is useful for everyday air quality forecasting, as well as for early warnings about extreme events, like the effects of wildfires," said Helen Worden, NCAR scientist and member of the research team, according to the UCAR website.
MOPITT provides one to two measurements over a given location per day. The geostationary fleet would allow multiple measurements of certain locations per day, making it possible to track emissions over rush hour versus lower traffic times in some urban areas.
The statistical technique used to test the geostationary fleet as a proof of concept was first developed to analyze data from MOPITT, which pioneered the measurement of carbon monoxide from space.

Terra: the EOS Flagship
Terra explores the connections between Earth's atmosphere, land, snow and ice, ocean, and energy balance to understand Earth's climate and climate change and to map the impact of human activity and natural disasters on communities and ecosystems.
Terra collects data about the Earth’s bio-geochemical and energy systems using five sensors that observe the atmosphere, land surface, oceans, snow and ice, and energy budget. Each sensor has unique features that enable scientists to meet a wide range of science objectives. The five Terra onboard sensors are:
- ASTER, or Advanced Spaceborne Thermal Emission and Reflection Radiometer
- CERES, or Clouds and Earth's Radiant Energy System
- MISR, or Multi-angle Imaging SpectroRadiometer
- MODIS, or Moderate-resolution Imaging Spectroradiometer
- MOPITT, or Measurements of Pollution in the Troposphere
Because Terra's five sensors share a platform, they collect complementary observations of Earth's surface and atmosphere. These varying perspectives of the same event can yield unique insights into the processes that connect Earth's systems.
