Abstract:
The National Snow and Ice Data Center (NSIDC) Atlas of the Cryosphere is a map server that provides data and information pertinent to the frozen regions of Earth, including monthly climatologies of sea ice extent and concentration, snow cover extent, and snow water equivalent, in addition to glacier outlines, ice sheet elevation and accumulation, and more. In order to support polar projections, the Atlas is divided into two separate map servers: one for the Northern Hemisphere and one for the...

The National Snow and Ice Data Center (NSIDC) Atlas of the Cryosphere is a map server that provides data and information pertinent to the frozen regions of Earth, including monthly climatologies of sea ice extent and concentration, snow cover extent, and snow water equivalent, in addition to glacier outlines, ice sheet elevation and accumulation, and more. In order to support polar projections, the Atlas is divided into two separate map servers: one for the Northern Hemisphere and one for the Southern Hemisphere. In addition to providing map images and source data through Open Geospatial Consortium, Inc. (OGC) protocols (WMS, WFS, and WCS), a dynamic web interface for exploring these data is also available 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. The development of this map server application was supported by NASA's Earth Observing System (EOS) Program under contract NAS5-03099 and was developed using MapServer, an Open Source development environment for building spatially-enabled internet applications.

Available at http://nsidc.org/data/smmr_ssmi_ancillary/monthly_means.html. Accessed 27 June 2008. Compiled from: Cavalieri, D., C. Parkinson, P. Gloersen, and H. J. Zwally. 1996. Sea ice concentrations from Nimbus-7 SMMR and DMSP SSM/I passive microwave data. Boulder, Colorado USA: National Snow and Ice Data Center. Digital media. Available at http://nsidc.org/data/nsidc-0051.html. Background: Monthly climatologies of sea ice concentration represent mean ice concentration percentages for each month over the entire time period 1979-2007, which is generated from passive microwave brightness temperature data derived from Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) and Defense Meteorological Satellite Program (DMSP) -F8, -F11 and -F13 Special Sensor Microwave/Imager (SSM/I) radiances at a grid cell size of 25 x 25 km using the NASA Team algorithm developed by the Oceans and Ice Branch, Laboratory for Hydrospheric Processes at NASA Goddard Space Flight Center (GSFC). A threshold of 15 percent concentration has been applied to the monthly climatologies.

Four separate layers are used to map land in the Southern Hemisphere: (1.) the Gridded Population of the World Version 3 (GPWv3) for everything but Antarctica; and NSIDC's MODIS Mosaic of Antarctica (MOA)-based polygons for Antarctica's (2.) islands, (3.) grounding line or continent (excludes the ice shelves), and (4.) coastline (includes the ice shelves and is given a different color than the previous three layers). These sources are documented and cited in their respective layers below.

Accessed 24 April 2008. Background: These outlines were hand-digitized from the Moderate-resolution Imaging Spectroradiometer (MODIS) mosaic of Antarctica (MOA) image map produced and distributed by the National Snow and Ice Data Center (NSIDC) at: http://nsidc.org/data/nsidc-0280.html. The coastline includes the ice shelves surrounding Antarctica while the grounding line excludes them. Coastlines for islands surrounding Antarctica are provided separately from the rest of Antarctica's grounding line.
