Mission: 
OIB
Mission Summary: 

Mission: ICESat-2 Devon
Priority: High
 
This is a new mission for 2019, primarily designed to sample the left and right beam pairs of ICESat-2 over the Devon Ice Cap and nearby undulating bare rock (likely to be snow-covered in April). The intention is to validate the geolocation of ICESat-2 footprints. The pattern of ICESat-2 ground tracks is nearly repeated, targeting the left beam pair on one pass and the right pair on the other. We validate range biases on the center beam pair during other missions. We also re-fly a pair of historical OIB lines crossing the ice cap, and one of the new ICESat-2 lines is a very close match to a 2012 CryoSat-2 line.
 
Our first mission for this campaign got us started on the right foot, with a promising forecast and light winds. Following a short transit across the northern end of Baffin Bay, we descended onto the Devon Ice Cap and began a series of roughly north-south back-and-forth lines along ICESat-2 ground tracks. We concluded the mission with an east-west transect along an historical OIB line, before returning to Thule AB. The ice cap, tidewater glaciers, landfast sea ice and snow-covered ground were all surveyed. We experienced a brief period of mild turbulence, but otherwise the flight was smooth. Most instruments performed very well, but the Headwall Nano-Hyperspec VNIR sensor had to be rebooted a few times and CAMBOT had a brief shutoff early in flight. ATM reported 100% return detection over target areas with improved IR performance at higher altitudes, and MCoRDS operated successfully in beam-steering + ping-pong mode for the duration of the mission with near-continuous observation of the bed when monitoring a single channel. We conducted roll maneuvers over Baffin Bay for MCoRDS and a ramp pass for ATM at 1500 ft AGL.
 
We surveyed the left and right beam pairs of 7 ICESat-2 ground tracks during this mission, listed below with their temporal latency relative to ICESat-2 cycle 3.
