Mission: ICESat-2 Arctic Ocean #2 (racetrack)
Priority: Baseline
This new flight for 2019 flies out-and-back along a single ICESat-2 ground track, selected and timed so that our aircraft and the spacecraft fly the track as closely as possible in time, and also with the track drift-corrected according to winds measured from the aircraft. The particulars of the technique we will use to fly the track will depend on knowledge of ICESat-2’s pointing accuracy just prior to the time of this flight. Options include out-and-back along the same or parallel and offset lines, varying the altitude of one or both lines, or even a four-segment line. The general idea is to obtain a composite swath wide enough to capture any likely pointing offset of the spacecraft. See Appendix D for more details on the design of these flights.
A sufficiently large cloud-free region in imagery and a decent forecast led us to select this baseline mission, another racetrack as a sufficiently long stretch of cloud-free regions was not available. We arrived on-station after two hours of transit to ICESat-2 RGT 218 only two minutes before the spacecraft passed overhead at 13:03 UTC on an ascending pass with clear skies overhead. As for ICESat-2 Arctic Ocean #1, we surveyed ICESat-2 beams 1L and 2L at 3500 ft AGL three times each with a 425-meter offset. Because winds were light and roughly parallel to the RGT, we did not correct for sea ice drift. We encountered some haze about 15 minutes into the flight. Unfortunately, ATM T7 experienced a malfunction during the first of the six lines and had about a 10-minute gap in data collection (~13:22-13:32 UTC), likely due to a temperature issue. Otherwise, skies were mostly clear and the mission was a satisfying success, with a few leads observed and lots of good data collected. ATM reported 100% data collection with the exception of the T7 malfunction. Even though MCoRDS was not operated during this sea ice mission, CReSIS was able to confirm during transit that their efforts further isolate the snow radar from MCoRDS interference succeeded. On the transit home, we chatted with thee K-12 classrooms from, including one from Project Manager Eugenia De Marco’s hometown in Argentina. Due to ceilings at Thule AB, we did not perform a ramp pass.
