attribute NC_GLOBAL summary String The OSI SAF Sea Ice data are developed and produced by the Norwegian and Danish Meteorological Institutes as a part of the OSI SAF project for EUMETSAT. Ice concentration is computed from atmospherically corrected SSMIS brightness temperatures, using a combination of state-of-the-art algorithms. The product series is operational since 2005 (version OSI-401-b since 26/05/2016). This product is complementary to the AMSR-2 global sea ice concentration product (OSI-408). The daily analysis of sea ice concentration is obtained from operation satellite images of the polar regions. This product is freely available from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) Ocean and Sea Ice Satellite Application Facility (OSI SAF).
