The extreme melt across the Greenland ice sheet in 2012 ...
The discovery of the 2012 extreme melt event across almost the entire surface of the Greenland ice sheet is presented. Data from three different satellite sensors – including the Oceansat-2 scatterometer, the Moderate-resolution Imaging Spectroradiometer, and the Special Sensor Microwave Imager/Soun...

The discovery of the 2012 extreme melt event across almost the entire surface of the Greenland ice sheet is presented.
