GODDARD SPACE FLIGHT CENTER

"The Interaction between the Troposphere and the Stratosphere: What are We Learning from Satellite Observations?"

The Aura satellite is the third and last of the big EOS observatories whose primary

mission is the study of the composition of the Earth's atmosphere. Aura was

launched July 15, 2004 in to polar sun-synch orbit 15 minutes behind Aqua. I will

give an overview of the mission and show some early results from the instruments.

These results include the first comprehensive chemical picture of the Antarctic ozone hole,

and the first day-to-day global measurements of tropospheric NO2, a pollutant and precursor for

tropospheric ozone.
