Global Sea Ice Concentration (SSMIS)

IDENTIFICATION
DescriptionIce 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).
