OUTLOOK FOR TOMORROW: Low pressure system still remains in the Arctic Ocean, meaning no viable sea ice mission options. Just South of Thule along the coast looks clear, similar to parts of NE Greenland, however it appears that central Greenland will have some clouds.
 
Mission: Zachariae-79N
Priority: High
 
This mission, previously flown during our spring 2019 campaign, was designed to sample the centerlines of both Zachariae and 79N glaciers. At these locations, OIB flies along 5 ICESat and 1 ICESat-2 ground tracks. ICESat ground tracks are the same as those flown by OIB in 2012, but moved farther inland due to the drastic break-up of the Zacharaie ice shelf. This mission also flies over a couple of PROMICE ground sites located just north of 79N Glacier. The transit out to these two glaciers is along a historical ATM line which dates back to 1994, and inbound from these two glaciers we fly farther north in order to fill in gaps of knowledge in the bedrock.
 
Overall, the mission today was a success, however the weather on the outbound and return from these two glaciers prohibited some data collection on these lines, which is what we anticipated based on forecasts and available satellite imagery. We expected and encountered low clouds on the outbound leg of this mission as we crossed over the Greenland ice sheet. For this portion we flew at 15,000 ft and could not collect data. At ~200 NM into this line, clouds cleared and we were able to drop down to 1,500 ft and begin data collection. Clear conditions with some intermittent high clouds were present at Zachariae and 79N Glaciers. Varying surface conditions were present over the snow and ice with melt channels, melt ponds, melt ponds beginning to refreeze, melting snow, dirty snow, and even bare ice. These types of conditions are extremely important to observe so we can improve interpretations of IS-2 returns from snow and ice surfaces in various stages of melt. On our return leg back across the ice sheet, clouds had moved into the area, prohibiting data collection for a short while, but at 58 degrees W clouds cleared and we were able to collect data for the remainder of the mission.
