| Comments: | The first ATTREX science mission in 2013 was very successful. The 24.5 hour flight in the Pacific tropical zone included numerous descents and climbs through very cold air. The only issue with the aircraft was a cracked glass cover on the HDVis camera, which was replaced after landing. | ||||

ATTREX - Global Hawk #872 02/05/13 - 02/06/13 Science Report
This flight provided several profiles in the tropics and subtropics, including multiple passes through air colder than 189 K. Extremely dry air was sampled in the upper TTL. The combination of satellite measurements and in situ data collected on this flight should allow evaluation of the dehydration occurring during the anomalously cold tropical tropopause conditions that prevailed during January 2013. Ice clouds were detected in the lower TTL, but not in the upper TTL associated with the very dry layers. The southernmost legs extended down to about 12.5 N between about 144 and 150 W.
