Airborne Study Surveys Greenhouse Gases in World Tour

The first deployment of one of NASA's most ambitious research studies of Earth's atmosphere will take place this July and August. The Atmospheric Tomography mission will take off aboard the agency's DC-8 flying laboratory on a 26-day journey from the North Pole down the Pacific Ocean to New Zealand and then across to the tip of South America and back north up the Atlantic Ocean to the Arctic.
