OUTLOOK FOR TOMORROW: A weak high pressure system is forming over central Greenland, pushing the clouds out of the center of the ice sheet. This scenario will likely cause clear skies in areas of northeast Greenland where we still have multiple land ice missions.  A sea ice mission looks possible on Monday, and the winds from this high pressure system flowing off north east Greenland will hopefully create clearing in the Lincoln Sea where very low latency ICESat-2 RGTs are located.
 
Mission: Northwest Coastal-A
Priority: Medium
 
This mission is a fairly new mission, having been flown last in Spring 2018. It begins by hugging the Northwest Coast from Thule all the way down south to near Upernavik and creates a grid pattern where each line moves inland roughly 30-35 km. This was designed to measure the ice sheet at different elevations up to 2000 ft and also at multiple latitudes to the south of Thule. During our summer melt campaign this is advantageous because we can sample different snow and ice surfaces at varying stages of melt and also sample some dirty ice in order to better understand how the ATM returns are scattered in different types of surfaces (saturated snow, melt ponds, bare and dirty ice, etc.)
 
The weather for today was ideal for flying and were exactly what the forecast models predicted. Light off-shore winds kept our mission flight lines clear. There were some clouds in Thule this morning, but they cleared out at mid-day. During the flight, lots of melting surfaces, melt ponds and melt ponds beginning to refreeze were encountered and measured. Due to these ideal flying conditions, OIB had nearly 100% of data collection. The only issue was with ATM for 10 minutes at the beginning of the mission due to an electronics failure. This issue was resolved quickly and data collection resumed.
 
AVIRIS also flew a few portions of our OIB lines today in order to measure some ‘dirty ice’ and melt conditions.
 
This particular mission did not follow any ICESat-2 ground tracks.
