How does NASA study air?
NASA missions collect data that tell us more about the composition, behavior, and quality of our air. Using the data, scientists develop or refine their theories about climate and its effects. They try to determine which long-term variations in climate result from natural causes and which are caused by people.
They monitor the ozone layer to detect changes, and they try to determine the causes and their effect on the planet. To test their theories, scientists send up new missions. They share what they learn so we can benefit from weather prediction and understand how we affect the air quality and how it affects us.
An international program called the Earth Observing System (EOS) monitors climate and environmental change on Earth. One important satellite within this system is the Aura satellite. This powerful research platform is providing first-ever daily, direct global measurements of low altitude or tropospheric ozone and many other pollutants that affect our air quality.
Two of Aura’s instruments use
new technology to see through low level ozone. This ability
promises a new era in tracking pollution sources and
destinations. To find out more about this satellite visit,
