ATTREX - Global Hawk #872 02/21/13 - 02/22/13 Science Report
This flight provided a survey of TTL composition in the eastern Pacific. As shown in the figures below, the flight plan took the aircraft southeast to 100 W and then due south to about 12.5 S. The flight included 24 profiles through the TTL, with multiple GWAS samples on each of the ascents. Clouds were sampled in the upper TTL near 5 N. Sharp structures we’re apparent in the water vapor concentration near the tropopause, and filaments of midlatitude lower stratospheric air were sampled in the tropics.
