OIB - HU-25C Guardian 10/20/15 Science Report
Mission: Falcon Southwest Coastal B (priority: medium)
This mission is one of three (with Falcon Southwest Coastal A and C), which together refly most of the the “Southwest Coastal A and B” missions flown in Spring 2015. These three flights work together in an interlaced (working upward from the coast) manner. This particular flight concentrates on the second and fifth lowermost of the coast-parallel lines, plus two additional lines covering a southwestern lobe of the ice sheet near Sukkertoppen.
Weather today was not ideal for ths flight. Our perusal of satellite images from the morning showed several patches of stratus cloud along the southwest margin of the ice sheet, but the progression of images in time also showed these clouds to be moving east. Because of that, we had reason to believe the area would improve by the time we got there. Also, with only one day of flight operations remaining in this campaign after today, we knew we might not get a better opportunity. As it happened, the low clouds had indeed departed the area for the most part, but some remained at the southernmost portion of the flight, where we lost several minutes of data as a result. Overall we estimate successful data acquisition across better than 90% of the flight.
All instruments performed well.
We conducted a ramp pass at 32,000' MSL just prior to landing.
