OUTLOOK FOR MONDAY: Tomorrow, Sunday (09/08/19), is a hard-down day for the OIB team and G-V crew due to a Thule airport closure. However, weather forecasts for Monday are promising for a low-latency sea ice mission, the first of this campaign. This mission will likely take place northeast of Greenland in the Lincoln Sea.
 
Mission: Northeast Grid 05 Prime
Priority: Low
 
Today’s mission was designed and flown for two reasons: 1) to measure the elevation of the ice sheet along two separate east-west lines that have numerous ICESat-2 crossovers as well as a ground track, and 2) sample areas of Greenland where we have limited information on the bed topography underneath the ice.
 
Although this land ice mission is only low priority it was our most viable option for today based upon the weather conditions. Forecasts for northern Greenland worsened overnight, with more low clouds than previously predicted, this was backed up with satellite imagery this morning, thus ruling out northern missions with higher priorities. Conditions at Thule were ideal, with no winds and clear skies, for take-off and landing enabling a ramp pass before landing. Through the majority of the mission, clear conditions dominated with some high cirrus clouds, allowing for optimal data collection. On the return to Thule from the Summit ridge line for roughly 150 NM, we did encounter some stratus clouds a few hundred feet above the surface. This caused about 30 minutes of a gap in the ATM data, however the snow radar data was not affected. The majority of the land ice was snow covered with no melt, covered with strastrugi and a few crevasses which were snow filled.
 
Overall, today’s mission was a success, with all instruments preforming well.
