NCDC releases new operational Climate Data Record for Sea Ice
Through a new operational Climate Data Record released this past month by NOAA’s National Climatic Data Center, users are now able to access the long-term record of sea ice concentration. NOAA’s National Snow and Ice Data Center developed the Climate Data Record of Passive Microwave Sea Ice Concentration from gridded brightness temperatures from the Special Sensor Microwave Imager passive microwave radiometers on the Defense Meteorological Satellite Program . This dataset combines concentration estimates from two algorithms developed at the NASA Goddard Space Flight Center and provides a consistent daily time series of sea ice concentrations in a polar stereographic projection, with a grid cell size of 25km x 25km, from July 9, 1987 through December 31, 2007. This data record will benefit a wide range of users including sea ice researchers, climate modelers, oceanographers, meteorologists, biologists, ecologists, native communities, civilian and government planners and policymakers.
