OIB - HU-25C Guardian 10/13/15 Science Report
Mission: Falcon Jakobshavn-Eqip-Store (priority: medium)
This mission is identical to the Jakobshavn-Eqip-Store flight conducted for the last several years and last flown in Spring 2015, but with the centerlines of Store, Eqip Sermia, Kangilerngata Sermia, Sermeq Kujalleq, Rink, and Kagerdlugssup Glaciers removed.
After several successive days of weather scrubs, we experienced another challenging meteorological situation this morning. During our 0630 weather briefing, most of southern Greenland was covered in cloud, much of it in several distinct layers. The lower portion of the Jakobshavn basin was largely clear, except for some isolated cirrus clouds. However the models indicated that this area too would deteriorate in short order as an incoming weather system pushed clouds into the sector. We decided to launch this mission anyway, knowing we would probably lose the eastern lines of the mission to a stratus deck. The weather we encountered was almost exactly what we expected. The cirrus clouds over the lower basin indeed became more widespread as the morning wore on, and the stratus clouds to the east prevented our acquiring more than isolated pockets of science data there. So we shortened the flight by removing the two easternmost lines. Our sensors were able to punch through much of the high cirrus on the remaining lines, but we also encountered an unexpected low cloud layer in the southern portions of the lines, which was probably associated with the incoming weather system For the shortened mission, we estimate that we successfully acquired data over 60% of the lines.
All instruments performed well today, with the exception of the cloudiness.
We conducted a ramp pass at 7000' MSL.
