Current State of the Arctic Hydrosphere

The Cryosphere at a Glance

This image shows a near real-time map of sea ice concentrations and snow extent in both the Northern and Southern Hemispheres. The image is processed from the Near Real-Time DMSP SSM/I Daily Polar Gridded Sea Ice Concentration and Snow Extent product (Near Real-Time Ice and Snow Extent, NISE) data set. This image is courtesy of the National Snow and Ice Data Center (NSIDC).


   
  
Current Sea Ice Concentration in the Northern Hemisphere:
Sea Ice Products at NSIDC

The image to the right, courtesy of the National Snow and Ice Data Center (NSIDC), depicts sea ice concentrations on 24 July 2004 for the Northern Hemisphere.

This near real-time product (typically available within 1-2 days following the time of image acquisition) is produced from the Near Real-Time DMSP SSM/I Daily Polar Gridded Sea Ice Concentration data set. For a more in-depth explanation of this operational product, and to view the most current sea ice concentration derived from this data set, click here.


   
  

NSIDC also has a sea ice product that is updated monthly, called the Sea Ice Index, which uses the Near Real-Time Sea Ice data (NRTSI). The image to the right shows the ice concentration for the Northern Hemisphere for June 2004. To view sea ice concentrations for the most recent month available, visit the Sea Ice Index page of the NSIDC.
