Mission Summary: 

Mission: Falcon Helheim-Kangerd (priority: high)

This mission is based on the Helheim-Kangerdlugssuaq mission last flown in Spring 2016. It has been shortened by removing all of the glacier centerlines from the area east of Sermilik fjord (including Midgard, Fenris, Glacier de France, and several others) and also the centerlines of two additional glaciers just south of Kangerdlugssuaq Glacier.

After the foggiest day in collective memory yesterday on the ground in Kangerlussuaq, today's local conditions were much better with high ceilings and no fog.  Most of southern Greenland was under the influence of high pressure and was clear, although weather models showed clouds moving in to the Kangerdlugssuaq Glacier region later in the day.  We indeed observed clear skies over and around Helheim Glacier, but the clouds north of Kangerdlugssuaq Glacier moved in earlier than we expected.  We responded by descending from 28,000' to 21,000', which placed us beneath most of the clouds, and we believe that we successfully captured data on the lower portion of the glacier.  We missed some of the region to the north of the Kangerdlugssuaq basin due to the clouds.

All instruments performed well.  The ATM T5 user interface "GUI" computer crashed during our approach to Kangerdlugssuaq Glacier, but the data collection computer continued operating normally.  The temporary unavailability of the GUI computer made it difficult for us to assess the quality of the ATM T5 data for the initial run down the glacier, but the GUI machine came back up for the second run back up the glacier, and the ATM data looked reasonably good for that run.  This led us to believe that both runs should produce usable data.
