When Typhoon Lan made landfall in Japan on Oct. 22, the Global Precipitation Measurement mission core satellite or GPM analyzed the storm and added up the high rainfall that it generated.

MOPITT Helping 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.
