Funding Source:Bruce Tagg - NASA - SMD - ESD Airborne Science Program
Purpose of Flight:Science
Comments:Local Kangerlussuaq weather delayed our departure this morning. The flight covered the baseline Southwest Coastal A line. Weather during the flight led to a decision to shorten the mission in order to maximize data collection and allow for a better flight opportunity the following day without violating crew work hour guidelines.

Mission: 
OIB
Mission Summary: 

Mission: Southwest Coastal A

Priority: Baseline    



This baseline mission is one of two (with Southwest Coastal B) designed to mirror the southeastern coast- parallel coverage in the southwest, along 2011 LVIS flight lines. This particular flight captures the lowest-altitude portion of this part of the ice sheet. We also overly a total of six PROMICE sites. 



After a four-hour delay due to local heavy fog in Kangerlussusaq, we were able to launch this baseline mission to clear skies directly above the dissipating fog. For dual-color ATM T7, prior to the start of this mission, the near-IR sensor was replaced with a larger bandwidth but narrower aperture sensor. This instrument was turned on and off several times during the course of the mission and no near-IR data were recorded as several  initial experiments were performed. During the western small grid, east of Sukkertoppen, we recorded some Headwall hyperspectral data across both ice and rock. We encountered expected but thicker clouds at the southeast end of the mission and were able to navigate through some of them, passing by the town of Narsarsuaq in doing so. Ultimately, however, they grew too thick and too close to terrain for us to navigate safely, and we were forced to abort the southern grid early, losing all of the four southernmost lines in the process. No signifiant melt was observed throughout the mission, although some small pocked of recent refreeze were observed. All instruments functioned well overall. MCoRDS reported a brief software GPS glitch. A N/S ramp pass at 2000 ft AGL was performed.
