Parallel ground tracks flown at approximately 1500 ft agl; tracks lined up in northwest to southeast direction and each was approximately 70 to 80 nm in length. Start stop times for each track as follows: 1. 1601Z – 1612Z 2. 1618Z – 1629Z 3. 1639Z – 1649Z 4. 1653Z – 1703Z 5. 1707Z – 1711 Z 6. 1720Z – 1734Z 7. 1738Z – 1752Z 8. 1801Z – 1808Z 9. 1810 – 1841Z (southeast to northwest track bisecting previously flown lines). Prior to climbing perform radar calibration check and then check new ATM guidance system performance while climbing. Start climb at 1846Z to FL410 for transit to SCCI. Perform calibration ramp pass at 1500 ft agl at 2303Z just prior to landing. Planned events: Continue science flights out of Punta Arenas, Chile

Mission Report (Michael Studinger, Mission Scientist)

Today's flight was a repeat of the identical 18 October 2012 flight, and its purpose was to obtain dh/dt measurements of Recovery Glacier. The mission is primarily designed along ICESat ground tracks. We also flew a crossing of the tributary channel entering the main Recovery channel from the west.

The forecast model indicated scattered clouds over Hull Land today, but satellite images, just a few hours old showed low stratus clouds over most of the area. The only other region worth considering was the Slessor and Recovery Glacier area. The Slessor Glacier has a higher priority, but low clouds were visible on the satellite image and the model predicted them to move slowly towards the survey area during the day. For this reason we decided to fly the lower priority Recovery Glacier mission because of the lower risk. The cloud front stayed just west of the survey area as we had expected and the weather conditions were perfect. We had about 20 kts winds at 1,500 ft AGL and blowing snow was visible at the surface for most of the time over the survey area.

LiDAR data collection started 10/25/2014 16:00 UTC and ended at 18:45 UTC. In total we collected 2.75 hours of science data. ATM recorded 100% surface returns.
