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.

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,
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.
