SMMR and SSM/I derived dates of Arctic sea ice surface melt/freeze
Listed in NASA Earthdata CMR
Description
Yearly maps of onset of early melt (earliest observed melt conditions), melt (melt conditions observed throughout from this point until freeze), early freeze (earliest observed freeze conditions), and freeze (freeze conditions observed throughout from this point on) for the surface of sea ice derived from SMMR - SSM/I data. See [Markus et al. 2009] for further details. Original data prepared in a polar stereographic projection, with 25 km grid spacing; data has been reprojected into a northern hemispheric Equal-Area Scalable Earth (EASE) grid [see: nsidc.org/data/ease/ for further details] with 25 km grid spacing.

These data were compiled in conjunction with the Sunlight and the Arctic atmosphere-ice-ocean system (Synthesis of Arctic System Science, SASS) project.
