| Abstract The PSI-SSMI level 2 product contains, for both north and south poles, polar sterographic 12.5 km resolution grids of sea ice concentration from the 85 GHz channel of SSM/I on DMSP, available since 1992. The daily maps are processed from the daily brightness temperature maps from NSIDC. The Artist Sea Ice (ASI) algorithm developped at University of Bremen (Germany) is used to processed daily sea ice concentration maps at 12.5 km resolution. The dataset covers the whole 85 GHz SSM/I mission. We are grateful to NSIDC (Boulder, Colorado) for the SSMI data. |

Data distribution
This product is distributed free of charge to the international oceanographic community. The data are stored as netCDF files. All fields, as netCDF zipped files, are available on CERSAT anonymous ftp site at IFREMER, in the directory ftp://ftp.ifremer.fr/ifremer/cersat/products/gridded/psi-concentration/data/. There is one file per day. The dataset is regularly updated, following data distribution by NSIDC. It is archived as follows :
