Mission Summary: 

Mission: Falcon Southwest Coastal B (priority: high)

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 2016. 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.

Southern Greenland was again totally clear at our early morning weather check today, and central Greenland was covered in extensive low clouds.  Both the US GFS and the Danish HIRLAM forecast models predicted that situation to basically reverse itself during the day, with skies clearing in central Greenland and high clouds moving into the southwest.  So we decided to hit the southwest in the morning and leave ourselves several options to the north and east for the afternoon.  We found that some altostratus clouds had moved in to the region of the ice sheet between the latitudes of Kangerlussuaq and Nuuk during the early morning, so we lost portions of the northern lines to these clouds.  Where practical, we descended variously to 22,000', 18,000', and 14,000' and successfully worked below most of them.  Overall, we estimate successful data collection for about 95% of the mission.

All instruments performed well.
