Description:
Aura’s four instruments study the atmosphere’s chemistry and dynamics, and enable us to investigate questions about ozone trends, air quality changes and their linkage to climate change. Aura’s measurements provide accurate data for predictive models and useful information for local and national agency decision support systems. Aura was the third in a series of large Earth observing platforms to be flown by the National Aeronautics and Space Administration (NASA) with international contributions. Aura along with EOS Terra (launched December, 1999) and Aqua (launched May, 2002) provide an unprecedented view of the global Earth system.
