OIB - HU-25C Guardian 10/21/15 Science Report
Mission: Falcon K-EGIG-Summit (priority: high)
This mission is a shortened version of the baseline-priority “K-EGIG-Summit” flight last flown in Spring 2015. This version retains the three upper IceSat-1 lines in the upper Jakobshavn catchment area, the western half of the EGIG line, and the overflights of the K-Transect sites near Kangerlussuaq, but eliminates the eastern portion of the EGIG line and the IceSat-1 and IceSat-2 cal/val lines near Summit Station.
Weather has been a problem for this high-priority flight since we arrived in Kangerlussuaq two weeks ago. A stubborn low to mid-level stratus deck has straddled Greenland's central ice divide for that entire period of time, making it impossible for our optical sensors to see the surface here. However, our two most-trusted weather models (ECMWF and GFS) predicted that this cloud deck would retreat north overnight last night and during the morning today. This morning as we perused the infrared weather satellite images collected overnight, we saw that this was exactly what was actually happening. For these stubborn clouds to finally dissolve on the morning of our last full day of flight operations brought to mind the Biblical story of the parting of the Red Sea (admittedly stretching a metaphor well past its breaking point). Happily we did not have an Egyption army in hot pursuit of us, but we did enjoy clear skies and a smooth ride throughout this flight. We believe that we achieved 100% successful data collection for the mission.
All instruments performed well.
We conducted a ramp pass at 5000' MSL just prior to landing.
Data volumes:
DMS: 23.3 Gb
Narrow Swath ATM: 19 Gb
FLIR: 1.9 Gb
total data collection time: 3.5 hrs
