Mission Report (Michael Studinger, Mission Scientist)

Today's flight is primarily a repeat flight, designed to measure dh/dt over the Wilkins Ice Shelf and Alexander Island along flight lines first established during the 2008 NASA-Chilean effort, with the IceSat-1 tracks over Wilkins added during a 2011 IceBridge flight. We also add a six-line, 10 km grid over the Fleming Glacier and remnant Wordie Ice Shelf, also for dh/dt purposes.

We did not have any satellite imagery this morning and made the decision to fly based on the AMPS and GFS models and advice from the forecaster in Punta Arenas. Both the AMPS and the GFS model (which is used by the weather office) failed to predict a widespread cloud layer between 7000 and 3500 ft, which made it very difficult for us to fly the survey. We managed to collect data over almost the entire mission plan except for about 35 minutes on the survey line and 15 minutes during the descent.

LiDAR data collection started 11/16/2014 14:30 UTC and ended at 20:36 UTC. In total we collected 6.1 hours of LiDAR data, of which a total of about 50 minutes was lost to clouds.
