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 scanning multichannel microwave radiometer (SMMR) - special sensor microwave/imager (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: http://nsidc.org/data/ease/ for further details] with 25 km grid spacing.
