The sea ice concentration product from the University of Bremen, Institute of Environmental Physics (IUP), is being retrieved with the ARTIST Sea Ice (ASI) algorithm, applied to microwave radiometer data of the sensor AMSR2 (Advanced Microwave Scanning Radiometer 2) on the JAXA satellite GCOM-W1. The data are gridded on a polar stereographic grid (EPSG code 3412, Antarctic) with 6.25 km grid resolution. The ASI algorithm was first implemented at IUP in 2002 for data of the sensor AMSR-E (Advanced Microwave Scanning Radiometer for EOS) on the NASA satellite Aqua (see the dataset of sea ice concentration from AMSR-E). Sea ice concentration data have been continuously produced since then, using AMSR-E data from 2002 until 2011, and AMSR2 data since 2012 (this data set). 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 dataset is being updated once a year with the new annual data. ...
