OIB - HU-25C Guardian 09/30/15 Science Report
Mission: Falcon Zachariae-79N (priority: medium)
This mission reoccupies the centerlines of the Zacharaie and 79N glaciers. It is similar to the Zachariae-79N flight planned (but not flown) for Spring 2015, except that we removed the IceSat-1 grid over the lower portions of the glaciers. We transit to and from the northeast region along a historical ATM lines dating back to 1994, and along an as-yet unflown master grid line.
Weather today was quite poor again, with northwestern Greenland completely obscured by clouds associated with a low-pressure system which came ashore overnight from Baffin Bay. A more powerful low-pressure system is forecast to approach the area during the day today and overnight, and it is likely that this system will close the Thule airport for at least portions of the next two days. Thus today may be our last flight opportunity until Monday. Fortunately, strong offshore flow and clear skies prevailed over much of northeast Greenland, so we selected this medium-priority flight for this afternoon, after flying the high-priority flight in the same region this morning.
All instruments performed well today. The cloudiness across northwestern Greenland prevented our instruments from collecting more than isolated data between Thule and the main ridgeline of the ice sheet, but we successfully collected data for all of the eastern half of the flightline. We flew the outbound transit at 35,000' MSL, the glacier centerlines at 29,000' MSL, and the westbound transit at 35,000' MSL.
We conducted a ramp pass at 3000' MSL.
