Current, Extended Mission
Mission Category: Earth Observing System (EOS), A-Train
Launch Date: July 15, 2004
Launch Location: Vandenberg Air Force Base, CA
Designed Life: July 15, 2010
Aura's four instruments study the atmosphere's chemistry and dynamics. Aura's measurements enable us to investigate questions about ozone trends, air-quality changes and their linkage to climate change. Aura's measurements also provide accurate data for predictive models and useful information for local and national agency decision-support systems.
