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 equator crossing at 1:45 PM. The satellite carries four
state-of-the-art instruments:
