Mission Summary: 

Mission: Falcon Mopup-Jakobshavn (priority: n/a)

This mission is intended to capture IceSat-1 groundtracks missed due to clouds on the earlier Thomas-Jakobshavn 01 and Jakobshavn-Eqip-Store missions.  The lines missed in those flights, and included here, are the uppermost (easternmost) lines, and thus this mission extends our existing measurements of the summer melt signal in the Jakobshavn basin higher on the ice sheet's flank.

Weather today was again almost ideal for this flight, with weak outflow, and clear skies, all along Greenland's west-central flank.  However a maddeningly persistent stratus deck remained in the area just bordering on the uppermost lines of this mission, and these clouds prevented us from flying our last remaining high priority mission, K-EGIG-Summit, this morning.  This stratus deck has been present in the same general area for two weeks now, and is the reason this mop-up mission was necessary in the first place.  There is a possibility that this stratus deck could move east during the morning and open the area for the afternoon, or possibly tomorrow.  For this mission, however, the stratus barely affected us at all.  It prevented data acquisition for perhaps 20 km along our extreme southeastern line.  In all, we estimate that we successfully acquired science data along 98% of the lines today.

Local weather in Kangerlussuaq this morning was clear but quite cold - 0 deg F at takeoff time.

All instruments performed well.

We conducted a ramp pass at 12,000' MSL just prior to landing.
