Upper Atmosphere Research Satellite (UARS)


NASA's UARS satellite, launched in 1991 from the Space Shuttle, was the first multi-instrumented satellite to observe numerous chemical constituents of the atmosphere with a goal of better understanding atmospheric photochemistry and transport. Many of these studies centered on the early understanding of ozone photochemistry. At that time, there were many open questions as to the details surrounding stratospheric ozone loss, especially with the processes related to the Antarctic ozone hole. UARS data were uniquely designed to address those questions.
