Mission Summary: 

Mission: Falcon Helheim-Kangerdlugssuaq Gap B (priority: low)

This mission is a shortened version of the Helheim Kangerdlugssuaq Gap B mission last flown in Spring 2015.  In order to accommodate the shorter range of the Falcon jet, we reduced the number of coast-parallel lines from six to four, and also eliminated two glacier centerlines in the center of the region.

The crystal-clear morning weather over the Helheim and Kangerdlugssuaq Glaciers deteriorated somewhat during the middle of the day today, with some high-altitude haze and widely-scattered cirrus moving in to that area.  Most of this was concentrated on the lowermost (easternmost) of the four survey lines between the two glaciers, and primarily to the north near Kangerdlugssuaq Glacier.  ATM and DMS were able to see through most of it.  We had fewer problems on the next three more inland lines.  Overall we estimate successful data acquisition across more than 90% of the mission.

All instruments performed well today.

We conducted a ramp pass at 19,000' MSL just prior to landing.

Data volumes:
DMS: 23.7 Gb
Narrow Swath ATM: 22 Gb
FLIR: 2.0 Gb

total data collection time: 3.7 hrs
