Mission K-EGIG-Summit
Priority: Baseline
This mission was designed to accomplish a number of high-priority tasks. First, we refly the van den Broeke “K-Transect” in the Russell Glacier catchment, consisting of several sites where comprehensive glaciological measurements are collected annually. We also fly the EGIG traverse line. We overfly the ICESat-1 track 412 Summit calibration site, and we fly two ICESat-2 ground tracks in the same area near Summit, with the expectation that these will become regular calibrations sites as well. For 2016, we added an overflight of a GreenTrACS core near IceSat track 0055. Finally we extend the coverage of the Jakobshavn basin upstream along ICESat-1 tracks, to capture continued inland progression of thinning there.
A middling forecast for Greenland as a whole but a decent forecast for this mission made for an easy choice, especially given that we had already surveyed some of the portions that were likely to be clouded over. We broke out of the clouds about halfway up the K-transect, but it was mostly clear throughout the ICESat lines, including those over Summit. By coincidence, we were able to observe an LC-130 taking off from Summit as we were conducting our final pass. Clouds east of Summit caused significant altimetry loss and we turned around early to rejoin the EGIG line where clouds dissipated. We hosted two visitors from Kangerlussuaq airport operations. All instruments performed well. Altimetry coverage was about 85%. We performed a low ramp pass at 1200 ft.
