What does Aura do?

Aura has several instruments that work together to measure particles in the air called aerosols, ozone gas and other gases in Earth’s atmosphere. Scientists use this information to study how these gases influence changes in air quality, and their links to climate change. Aura brings up the rear in the “A-Train” satellite constellation. NASA’s “A-Train” is a group of satellites that orbit one right after the other, like train cars on a track.
