The Arctic Sea Ice Seasonal Change and Melt/Freeze Climate Indicators from Satellite Data, Version 1 data set is now available at the National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
This data set contains melt-season indicators that can be used to delineate various stages in the summer melt and freeze-up period of sea ice from 1979 through 2017. The data were primarily derived using Sea Ice Concentration (SIC) observations from the NOAA@NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration data set and brightness temperature observations from the DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures data set. These data are gridded on the NSIDC northern hemisphere polar stereographic grid at 25 km. These data are available as part of an early release, and as such, minimal documentation is currently available. An increased Level of Service and more detailed documentation will become available in the future.
