Mission Summary: 

Yesterday we flew 2 full missions plus a portion of a third mission. Linking these missions took advantage of good weather over a large portion of our operations area, and by doing so we were able to get one of two baseline missions for this campaign completed. The missions we flew are:
 
1) Land Ice – ITASE 67 / South Pole - McMurdo (priority: High)

This mission flies the ITASE 2006-2007 traverse route between McMurdo and South Pole Station.

2) Land Ice – Hamilton Line 1 / South Pole (priority: Baseline)

This flight’s purpose is to sample the surface topography at the southern apex of more than half of all planned IceSat-II orbits. In this way, we can provide “ground truth” for every IceSat-II orbit with just two flights, including the companion Hamilton Line 2 flight. The vertical stability of the surface must also be quantified for this approach to succeed, and this flight provides measurements for this purpose. Specifically this flight samples the ground tracks on the side of the Antarctic plateau primarily facing the Siple Coast and the Transantarctic Mountains. It also covers the Brunt-led 88S traverse route, shown on the map in light gray, overlapping with the Hamilton Line 2 flight there and for a short portion on the opposite side of the Pole. The flight is named in honor of Gordon Hamilton. 
 
3) Land Ice – TAM East / South Pole (priority: High)

This mission flies the centerlines of the Reedy Glacier and Mercer Ice Stream in the east, and Scott Glacier in the west. We flew the centerline of the Scott Glacier down to the Ross before breaking off and transiting back to McMurdo.
 
Flight conditions were good at McMurdo and Pole where we landed for a refuel halfway through the flight. Light winds and air temps ranging from -9 C at McMurdo to -27 C at Pole. We did encounter some down glacier winds on the Scott Glacier centerline with light turbulence, otherwise smooth flight conditions. Scattered low lying clouds of ice crystals were encountered for roughy 10% of the coverage on the Plateau, and in these places the lidar did not get returns from the surface. This affected the ITASE 67 line more than the Hamilton Line.
 
KU radar and UAF lidar performed well throughout, no issues. A super huge thanks to our pilots Sean and Scott for coming up with this excellent plan which resulted in extreme efficiency by linking these coverages.
