NASA drones to explore climate change effects above the atmosphere

climate-changeSix ATTREX flights are scheduled to take place between mid-January and mid-March. Those will be followed by flights over Guam and Australia next year.

NASA To Use Drone For Climate Research, Information Week Government, Patience Wait, 11 Jan 13,  NASA this month will begin using a drone capable of flying 12 miles above the Earth’s surface in an effort to understand how atmospheric changes affect climate…… NASA’s new project is called the Airborne Tropical Tropopause Experiment, or ATTREX. The tropopause is the atmospheric layer between the troposphere, which is the lowest portion of the atmosphere, and the stratosphere. “There are vortices in the atmosphere that spin off the North Pole over the Pacific,” said Don Sullivan, a NASA employee working on the IT portion of ATTREX. “A lot of stuff that originates in Asia winds up in North America. We don’t know if it’s original material” or chemically compounded in the atmosphere.

The Global Hawk is capable of flying at 65,000 feet and staying aloft for 30 hours, allowing for air sampling over an extended period. It has been outfitted with about a dozen scientific instruments and sensors to measure trace gases, temperature, water vapor, radiation and other cloud properties…..

Moisture and chemical composition are variables in Earth’s climate. According to NASA, the processes that cause fluctuations in atmospheric compounds are not well documented, and the ATTREX project aims to fill that void. A better understanding of the interactions taking place in the atmosphere could improve scientists’ ability to forecast global climate conditions. NASA has several other projects underway to research climate change, and it will co-host a Climate Palooza on Jan. 24 with the University of Southern California……

Six ATTREX flights are scheduled to take place between mid-January and mid-March. Those will be followed by flights over Guam and Australia next year.

Drones are a cheaper way for NASA to pursue some aspects of its mission, compared to rocket launches. ATTREX is an example of the agency’s Venture-class projects, which are designed to be implemented rapidly and at lower costs…. http://www.informationweek.com/government/information-management/nasa-to-use-drone-for-climate-research/240146117
