Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. Determining effective strategies for mitigating surface ozone (O 3 ) pollution requires knowledge of the relative ambient concentrations of its precursors, NO x , and VOCs.

DISCOVER-AQ project to begin flights to enhance measurement of ground-level air-quality from space

Green Car Congress

The flights will be supported by the US Environmental Protection Agency (EPA) and will aid EPA in monitoring pollutants. The fundamental challenge for satellites measuring air quality is to distinguish between pollution near the surface and pollution higher in the atmosphere. Measuring pollution from space.
