  Recent Accomplishments: Atmospheric Composition
Aura's view from space enables us to understand the long-range pathways of pollutants, and early research results using MLS measurements of carbon monoxide have begun to quantify the role of strong convective weather systems and long-range transport of pollution.
Thus, daily satellite observations and continuous in situ measurements are needed to observe the emission and transport of dense aerosol plumes downwind of populated and polluted regions and regions with vegetation fires.
Satellite data from Total Ozone Monitoring Spectrometer (TOMS) instruments have been essential for deriving global trends in UV radiation levels and resolving critical questions about the impacts of increased UV radiation due to stratospheric ozone depletion and changes in aerosols and clouds.

 Satellite will study atmosphere | www.azstarnet.com ®
The Aura satellite will study the composition of the atmosphere to learn how pollution moves, the extent of recovery by the stratospheric ozone layer, which has been depleted, and how the climate is changing.
"Aura is focused on a fraction of the remaining 1 percent, the trace gases and aerosol particles that are almost as important as oxygen itself in sustaining life on Earth," DeCola said.
"What Aura will do is help us to understand how stratospheric ozone will respond, given the declining abundances of ozone-depleting chemicals in the atmosphere due to the success of international treaties, while at the same time we have increasing abundances of greenhouse gases that can delay the recovery of ozone," he said.

The emerging capability for satellite observations of the troposphere is profoundly changing the design of research aircraft missions for tropospheric chemistry.
