Mission Summary: 

Mission: Southeast Coastal A (priority: baseline)

This mission reflies a 20-km coast-parallel grid along the southeast Greenland coast, enabling direct measurement of dh/dt in the catchment areas of the many major glaciers in the area across a range of surface elevations. This mission plan originally included centerlines of the Fritdjof and Ikertivaq Glaciers, but we had to remove these lines to shorten the flight by almost one hour.  This in turn was necessitated by yesterday's hydraulic leak, which required a lengthy evening repair effort by members of the flight crew, and this delayed our takeoff today by several hours. This flight retains a high priority for 2016 because it continues an intra-annual time series with the spring and fall 2015 campaigns along these lines.

The Iceland Low, a semi-permanent storm system usually situated near Iceland and the Denmark Strait, had moved well to the north over the past several days.  At the same time, somewhat rare high pressure had been building over the Denmark Strait overnight.  This created an ideal meteorological setup for flying in southeastern Greenland, which enjoyed an absence of both clouds and high winds (and the associated near-surface turbulence) today.  Most other science targets reachable from Kangerlussuaq, including the Jakobshavn area, were clouded, making the selection of this baseline mission an easy one.  We encountered low clouds only over roughly the westernmost 100 miles of the east-west transit lines, plus a few low clouds at the extreme southern end of the southeastern lines.

All instruments performed normally today.  However, the aircraft experienced a partial recurrence of yesterday's hydraulic leak less than two hours into today's mission.  The flight crew was able to isolate and stop the leak in short order, but not before some of the hydraulic fluid escaped and partially coated the exterior of the ATM and DMS nadir windows.  Rob Russell and Alexey Chibisov of the ATM team responded by increasing the laser power throughput of the ATM to its maximum level, and by this method successfully obtained ATM data throughout the mission.  DMS imagery suffered from the fouled window to a noticeable degree, but continued operating throughout the flight.

Overall, we estimate successful data collection across 90% of the mission, with only the western portions of the two transit lines experiencing significant data loss.

We conducted a ramp pass over Kangerlussuaq at 1500' AGL today.
