Flight Mission Details
Overview:
This was the 9th flight out of Ponca City. Preflight goals focused on measuring BRDF over the Southern Great Plain Central Facility (36.60°N, 97.48°W) -- CF. This flight was coordinated with Terra overpass (17:49 UTC), ER-2 (19:20 UTC) and Aqua (19:27 UTC). BRDF measurements were made at several levels (600' agl, 1500' agl, 6000' agl, 12000' agl, and 13000' agl). There were scattered clouds with base height of about 4000'.
J-31 Crew - David Thrasher (Pilot 1) & Scott Kaiser (Pilot 2).
Cabin Crew - Charles Gatebe (Flight scientist; GEST/GSFC) and Robert Billings (UC Santa Cruz/NASA Ames).
