The National Aeronautics and Space Administration (NASA), the European Space Agency (ESA) and the Republic of Korea are working together on a global satellite constellation of three space-based instruments that could track global pollution on an hourly basis. These air quality satellites will measure pollutants, including ozone, nitrogen dioxide, formaldehyde and tiny atmospheric particles called aerosols in order to enhance our understanding of air quality and air pollution. To date, air quality satellites have collected data only once a day. These three new instruments will provide hourly, highly detailed and near-real-time data that will improve air quality science and forecasting around the world, in particular around the most densely populated areas of the Northern Hemisphere.
Collecting data hourly will allow...more
