Mission Summary: 

Mission: Falcon Umanaq B (priority: high)

This mission is a shortened version of the Umanaq B flight last flown in Spring 2015.  It has been shortened to accommodate the shorter range of the Falcon aircraft by paring the original six coast-parallel lines down to four, and by removing the short lines over Disko Island and the Nussuaq Peninsula.

We expected better weather than we actually saw today.  Morning satellite images showed only a few isolated bands of cirrus clouds near Kangerlussuaq.  These cirrus bands were associated with a low pressure system encroaching on southwest Greenland from the Davis Strait.  The coastal area along Disko Bay and to the north was completely clear.  By the time we reached the Jakobshavn Glacier area, however, the cirrus bands had moved north, and substantial haze had also moved in.  Farther north along our primary Umanaq lines, the weather was clear except at the southern extremities of these lines, and most of our data loss was in the transit lines across the Jakobshavn basin.  Overall, we estimate successful data collection along more than 90% of the mission.

All instruments performed well today. 

We conducted a ramp pass at 10,000' MSL.

Data volumes:
DMS: 17.5 Gb
Narrow Swath ATM: 24 Gb
FLIR: 1.9 Gb

total data collection time: 3.6 hrs
