With winter closing in, a new NASA airborne campaign got under way October 31, 2013 in Greenland. For the first time, the Laser Vegetation Imaging Sensor, or LVIS, is flying aboard NASA's new C-130 aircraft to measure the island's ice following a summer's melt. This data will complement measurements the LVIS instrument has taken in previous springtime campaigns as a part of Operation IceBridge, a six-year multi-instrument survey over both Arctic and Antarctic ice.
