NASA’s STAQS mission is mapping air pollution in 3D across several megacities:

From city street to stratosphere 🏙️🛫🛰️
This summer, NASA’s STAQS mission is mapping air pollution in 3D across several megacities: New York City, Chicago, Los Angeles and Toronto. The goal is to map air pollutants from the ground to the upper troposphere, track where they come from and how they change hour by hour, and identify neighborhoods disproportionately exposed to unhealthy air.
The data STAQS collects will complement the new measurements from NASA’s TEMPO satellite, which measures hourly daytime air pollution over North America. TEMPO launched in April 2023.
