OIB ATM sitrep Nov 5, 2016 pm

All,
 
A successful Getz 5 mission was completed under clear blue skies and calm winds today. All science instruments reported good data collection. The ATM T5 collected about one hour of high altitude data on both the inbound and outbound transits over sea ice, and ATM T6 collected wide scan elevation data over the entire low altitude science lines.
 
OIB will take a “hard down” rest day tomorrow; we’ll rest up, relax, and recharge. Antarctic weather forecast look good for early next week and we hope to begin another string of missions.
