NASA-led mission to map air pollution in 3D over megacities

This summer, as wildfire smoke blankets large swaths of North America and heat-stoked summer haze reaches its seasonal peak, NASA and its partners are deploying several new tools to observe air quality and pollution from the street to the stratosphere. Launched into orbit earlier this spring, TEMPO, short for Tropospheric Emissions: Monitoring of Pollution, is the first satellite instrument that will measure air quality over North America hourly (during daylight hours) and at the resolution of a few square miles. Its field of view stretches from Mexico City to central Canada and from the Atlantic Ocean to the Pacific. NASA's newest atmospheric chemistry instrument will soon begin transmitting data for scientific use.

    The NASA-led mission to map air pollution in 3D over megacities is a commendable initiative. Air pollution is a growing global concern and has detrimental effects on both human health and the environment. By employing advanced technologies and satellite observations, this mission can provide valuable data and insights into the sources, patterns, and impacts of air pollution in densely populated areas. The 3D mapping approach will allow for a more comprehensive understanding of how pollutants disperse and accumulate, enabling policymakers, urban planners, and researchers to develop more effective mitigation strategies. This mission represents an important step towards improving air quality and fostering sustainable development in megacities around the world.
