OIB - HU-25C Guardian 10/05/15 Science Report
Mission: Falcon Sea Ice East (priority: high)
This flight is based on the western “bunny ear” of the spring 2015 “ZigZag East” mission, with the flight line adjusted slightly to improve coverage over what may be some unusually young and thin ice east of Cape Morris Jessup. The portion of this flight running through the northern Nares Strait is coincident with a SIMPL flight line from their August 2015 campaign. We also underfly a contemporaneous CryoSat-2 orbit at the far eastern end of the flightline, near Cape Morris Jessup.
Weather over the eastern Lincoln Sea continued to improve during the day today, as the south wind descending from northern Greenland's ice sheet dried the air mass and dissolved the low clouds observed in the morning satellite image. We encountered some haze throughout the flight and a few minutes of low-level stratus at the northeastern apex of the flightline, but otherwise had no problems with visibility to the surface. We successfully obtained data over at least 95% of the flight line.
All instruments performed well during the flight. Since we flew north and east during Thule's afternoon period, we again flew away from the sun and encountered sun elevations below the horizon at the eastern sector of the flight line. This was unavoidable since we needed to time this flight to coincide with the CryoSat-2 overpass. DMS captured useable imagery even at the lowest sun angles, however.
The CryoSat-2 spacecraft flew directly over us, overtaking us from behind, at 17:39:48z, on orbit #29114 (and between our waypoints 29114C and 29114D). We timed our entire suite of activities today to coincide with this event, and it worked out perfectly.
We conducted a ramp pass at 5000' MSL.
