Ice Sheet Analysis
Surface melting was significantly more frequent and more extensive than average on the Greenland Ice Sheet in July, especially around the northwestern coast. July also saw high air pressure over the entire island and warmer-than-average temperatures in the northwest.
Ice Sheet Analysis
Warm conditions arrived on the Greenland Ice Sheet in late June, causing a sudden spike in melting that increased in early July and led to a sharp reduction in surface albedo (brightness of the snow). However, as of mid-July surface melt remained less extensive than during 2012, the record melt summer.
Feature Story
The National Snow and Ice Data Center (NSIDC) is well known for its data on frozen parts of the Earth. But soon, it will have data on something more warm-blooded.
Ice Sheet Analysis
The Greenland Ice Sheet began 2015 (January 1 to May 31) with cooler-than-average conditions and higher-than-average snowfall accumulation, related to a near-continuous positive North Atlantic Oscillation (NAO) index pattern through the period.
