Sea ice concentration distribution in the northern (left) and southern (right) hemisphere for February 10 and September 10, 2007, respectively. Note that sea ice concentrations are cut off at 15%.
This data set is only available for a restricted user group, please contact us if you want to access these data.
RESTRICTED only accessable in ZMAW net or via CliSAP login What does that mean?
Scanning Multichannel Microwave Radiometer (SMMR) and Special Sensor Microwave/Imager (SSM/I) data have been used to produce a new global sea-ice concentration data set gridded onto a Lambert-Azimuthal Equal Area grid with 12.5 km grid resolution. The sea ice concentration data available here have been computed using re-processed brightness temperature observations that have been corrected in advance for inter-sensor differences. The sea-ice concentration retrieval algorithm used has been carefully selected based on the results of an algorithm intercomparison study. The data set comprises the sea ice concentration, an error estimate, and a quality flag for each day and grid cell.
The Product User Manual and the Validation Report give details about the sea-ice concentration retrieval, additional filters, optimization procedures, and the error estimation as well as some aspects about the validation.
The figure on top of the page give examples of the sea-ice concentration distribution in the northern and southern hemisphere for both summer and winter on the respective hemisphere.
