Mission Summary: 

Mission: K – EGIG – Summit
Priority: Baseline
OIB completed the final baseline mission out of Kangerlussuaq: K – EGIG – Summit.  The mission accomplishes several important tasks including extending coverage into the uppermost part of the Jakobshavn catchment with ICESat and ICESat-2 tracks and hitting the key validation Summit validation traverse site along ICESat track 412 and ICESat-2 track 879.  Finally, we hit two major field surveys: the K-Transect within the Russell Glacier catchment and the EGIG line.  For this campaign, the eastern portion of the EGIG line was shortened to accommodate for more ICESat-2 tracks near Summit and a single ICESat track was replaced with an ICESat-2 track in the upper Jakobshavn catchment.  A total of six ICESat-2 tracks were flown, two of which were swapped (see notes below) to minimize the timing between OIB and IS-2 data collection (the attached map has been updated accordingly).
Due to a local event at the airport, we incurred a delayed takeoff with an expected arrival time after 6 PM.  As a result, we were able to survey a portion of the Southwest Glaciers 01 mission over the Sukkertoppen Ice Cap just west of Kangerlussuaq in addition to the entire K-EGIG-Summit mission.
The flight was very smooth, although quite featureless, over the interior ICESat / ICESat-2 tracks.  As expected, we encountered clear skies for nearly the entire route, including Summit, which had been fogged in for several days prior.  Temperatures dropped a few degrees over the past few days, so many of the melt ponds developed a thin layer of ice on top.  We noted evidence of surface meltwater pooling up to ~26 km inland of Russell Glacier and ~4100 feet in elevation.
Headwall SWIR did not operate today, but otherwise all instruments worked well. ATM estimates 100% altimetry data recovery.  We performed a ramp pass at 2500’ prior to landing.
