A pair of images showed the extent of surface melt on Greenland's ice sheet on July 8 (L) and July 12 (R). Measurements from three satellites showed that on July 8 about 40% of the ice sheet had undergone thawing at or near the surface. In just a few days, the melting had dramatically accelerated and an estimated 97% of the ice sheet surface had thawed by July 12.
The areas in light pink correspond to "probable melt" where at least one satellite showed surface melting. Dark pink areas indicate "melt" as detected by two or three satellites.
