AB: A new algorithm for identifying melt extent and melt intensity on the Greenland ice sheet has been developed utilizing the am and pm orbital data from the DMSP passive microwave satellites. The new approach is utilized to develop a set of probability surfaces describing the likelihood of any given pixel melting at some point in time during the melt season. The 2002 and 2003 melt anomalies are analyzed in terms of their probability of occurrence given the previous 22 year satellite record. The general synoptic conditions contributing to the melt anomalies are described based on the GC-NET network of automatic weather stations and NCEP/NCAR reanalysis.
