Passive microwave satellite data are used to map snowmelt extent and duration on the Greenland ice sheet. The total melt extent of the ice sheet, experiencing at least 1 melt day between April 1 - September 25 shows a new record extent in 2007 for the 29-year long time PM data set. The 2007 melt extent exceeds the previous record of 2005 by 10%.
