Higher surface mass balance of the Greenland ice sheet revealed by high-resolution climate modeling
High-resolution (∼11 km) regional climate modeling shows total annual precipitation on the Greenland ice sheet for 1958-2007 to be up to 24% and surface mass balance up to 63% higher than previously thought. The largest differences occur in coastal southeast Greenland, where the much higher resoluti...
