We previously wrote about the Met Huts in Kangerlussuaq and Thule, Greenland –- the ground-based GPS stations that help scientists to ensure that GPS information collected on the aircraft is as accurate as possible. Kyle Krabill is back in Thule for the Arctic 2011 campaign making sure hut operations run smoothly.

“Took a couple pictures this morning [March 17] from my view here at the hut. Sunrise is getting earlier by 13 minutes or so each day. The guys are flying another mission again today. Had a little warm front come through last night and its up to a balmy -17 (if you're out of the wind)”
