AMSR-E ASI sea ice concentration data, Antarctic, version 5.4 (NetCDF) (June 2002 - September 2011)


The sea ice concentration product from the University of Bremen, Institute of Environmental Physics (IUP), has been retrieved with the ARTIST Sea Ice (ASI) algorithm, applied to microwave radiometer data of the sensor AMSR-E (Advanced Microwave Scanning Radiometer for EOS) on the NASA satellite Aqua. The data are gridded on a polar stereographic grid (EPSG code 3412, Antarctic) with 6.25 km grid resolution. After the failure of AMSR-E in 2011, the ASI algorithm has been applied to the data of the sensor AMSR2 (Advanced Microwave Scanning Radiometer 2) on the JAXA satellite GCOM-W1 (see the datasets of sea ice concentration from AMSR2). This means that sea ice concentration data have been almost continuously produced since 2002, using AMSR-E data from 2002 until 2011 (this data set), and AMSR2 data since 2012. As several details of the processing chain have changed over the years, in 2018, all ASI ice concentration data for the Arctic and Antarctic based on AMSR-E and AMSR2 have been reprocessed with exactly the same parameters, settings and software. The result are ASI data, version 5.4. The details are explained in the ASI User Guide (

PLEASE NOTE:In the summer months, masking out of spurious sea ice (which can be caused by weather effects) was not correctly applied. The masking is described in section 3.5 "Maximum ice extent masking" of the ASi User Guide, As a result, spurious sea ice can show up in summer in regions that are ice.-covered in winter.A newer version of this data is available, please see "Replaced by" reference.
