Layer Abstract

Maslanik, J. and J. Stroeve. 1999, updated daily. Near real-time DMSP SSM/I daily polar gridded sea ice concentrations. Boulder, Colorado USA: National Snow and Ice Data Center. Digital media. Available at http://nsidc.org/data/nsidc-0081.html. Background: This data set provides a near real-time map of sea ice concentrations for both the Northern and Southern Hemispheres. Near real-time passive microwave brightness temperature data from the Defense Meteorological Satellite Program (DMSP) F13 Special Sensor Microwave/Imager (SSM/I) are received daily from the Marshall Space Flight Center (MSFC) and gridded onto a polar stereographic grid. Investigators generate sea ice concentrations from these data using the NASA Team algorithm. These data are available via FTP for the most recent three to six months, and are retained on the FTP site until NSIDC's Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Passive Microwave Data (preliminary data) become available for the same time period. These data are primarily meant to provide a best estimate of current ice and snow conditions based on information and algorithms available at the time the data are acquired. Near real-time products are not intended for operational use in assessing sea ice conditions for navigation and should be used with caution in extending the sea ice time series in NSIDC's Sea Ice Concentrations from Nimbus-7 SMMR and DMSP SSM/I Passive Microwave Data.

Server Abstract

This map server from the National Snow and Ice Data Center (NSIDC) provides cryospheric data and information pertinent to the Northern Hemisphere. Map images and source data are provided through Open Geospatial Consortium, Inc. (OGC) protocols (WMS, WFS, and WCS). For other related OGC data sets from NSIDC, see also the Atlas of the Cryosphere at: http://nsidc.org/data/atlas/. If you have questions, comments or suggestions, please contact NSIDC User Services at +1.303.492.6199 or nsidc@nsidc.org.
