Purpose of Flight:Science
Comments:OIB Barrow science flight number two. Flew low level portion over a group of 4 ice pack buoys and then attempted a Cryostat under flight. Weather was extensive areas of low altitude clouds from about 1000 feet to the surface with occasional clear sky breaks that allowed good data collections for both instruments.

Mission: 
OIB
Mission Summary: 

This line was designed to continue to provide broad geographic coverage for the campaign while entering into a consolidated area of the ice pack, it took advantage of a small hole in the clouds which was forecast to close up shortly after we finished up the mission. We also targeted a cluster of buoys from the University of Washington, and under-flew a CryoSat-2 orbit which passed over at 22:34Z just before we finished the survey line.

We encountered clouds after descending to the first line towards the buoys, some small gaps were seen in the clouds at times which increased in frequency and transitioned to generally clear skies as we closed in towards the buoy location. The ice in this area was largely consolidated with lots of melt ponds on the surface with much good data was during this line.

The first pass across the buoys was conducted at 21:01Z, a second pass over the buoy location was done at 21:06Z, these were conducted under mostly clear skies. Remnants of human activity with orange and brown material were seen from the aircraft near the buoy site.

The cloud cover increased along the line between the cluster of buoys and CryoSat-2 track, given the nearly solid concentration of clouds towards the end of the line we cut it short about 30 nm and proceeded to the second waypoint (3224B) along the CryoSat-2 orbit. We entered the CryoSat-2 orbit at 21:51Z, a short time before the satellite passed overhead. Cloud cover was heavy initially and no laser returns were obtained. The clouds began to clear enough about a third of the way down the line for some data to be collected, with more frequent gaps in the clouds towards the final third of the line.
