Aura

 Welcome to the EOS Aura Data Support Web Site at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC). Aura is the EOS chemistry mission which aims to answer three important questions: is the ozone layer recovering, is air quality getting worse, and is the Earth's climate changing? Aura will continue the long term series of atmospheric chemistry measurements made by earlier missions. The Aura spacecraft operates in a 705 km sun-synchronous polar orbit, with an ascending equ ator crossing at 1:45 PM. The satellite carries four state-of-the-art instruments:
