OUTLOOK FOR TOMORROW: Unfavorable conditions still linger for a sea ice mission due to a strong low pressure system located in the Arctic Ocean, however missions in Northeast Greenland look promising.
Mission: ICESat-2 North
Priority: High
This mission was designed to fly IS-2 ground tracks over a wind range of ice and melt regimes of ice. The east-west lines of this mission are also designed to capture as many ascending and descending IS-2 crossovers as possible. Also during this mission a flowline of Petermann Glacier is also flown, collecting data along the same line as OIB and ATM missions in the past.
The weather today was exactly as predicted in forecast models (>4 days ahead!) as well as what was shown in the imagery. Clear skies, light winds, no turbulence were present throughout the mission; allowing 100% successful data collection, except for the intermittent outages with Headwall.
During the mission today, OIB on the NASA G-V flew in tandem with AVIRIS on the B200, while ICESat-2 passed directly overhead (zero latency). This occurred on the IS-2 RGT 1048 (center beam) where the IS-2 spacecraft passed directly overhead at 17:07:01 UTC with clear skies. This RGT was situated over low-lying ice just south of Humboldt Glacier, with abundant evidence of melt, most of it partially refrozen, along the line. This allowed for excellent data collection of multiple surface types throughout different stages of melt.
