Mission Summary: 

Mission: Falcon Southeast Coastal A (priority: high)

This mission is one of two (along with Southeast Coastal B) which are designed primarily to refly the “Southeast Coastal” mission from Spring 2015. These two flights work together in an interlaced (working upward from the coast) manner. This particular flight concentrates on the first and third lowermost of the coast-parallel lines. It transits to the east coast along a line from a different mission also flown in Spring 2015, in order to expand post-melt coverage farther south.

Our launching of this mission was another in a series of difficult weather-based decisions.  The most recent satellite image available when we had to decide whether to launch or scrub showed that the southern portion of this line was clear, but the northern and northeastern portions were clouded.  However several weather models showed that the clouds to the north would vacate the area during the afternoon.  These models also led us to believe we would not get a better chance to fly this high-priority area for several more days.  So we decided to launch.  Between decision time and launch time, a new satellite image arrived and showed that the clouds had indeed largely cleared the area, which relieved a great deal of stress.  In the end, the entire eastern portion of the mission was completely clear, and only the western halves of the east-west transit lines were clouded.  As so often happens, the clouds stopped almost exactly at the ice divide, which also separates upsloping (and cooling and condensing) air flow from downsloping (warming and drying).

All instruments performed well.

We did not conducted a ramp pass due to poor weather.
