Led by NASA's Ames Research Center, ATTREX focused on small changes that may significantly impact our climate. The ATTREX team checked out 11 specialized instruments on a Global Hawk during several flights from NASA's Dryden (now Armstrong) Flight Research Center. The Global Hawk aircraft are operated and maintained by Dryden Flight Research Center, Edwards, CA.
