Global Sea-Ice Concentration (SSMIS)

Operational (input data is unstable, please use OSI-408-a instead) Near real time product

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. This product is complementary to the AMSR2 global sea ice concentration product (OSI-408 series).

Accuracy Requirements
Target accuracy : 10 % for NH-product. 15 % for SH-product
Verification/validation method : Comparison with high resolution manual ice charts (available between twice a week and once a week): the performance shall be validated for only the “ice” and “water” cases, separately.
Applications and users
Usage : NWP and Ocean/Ice models, operational Met and Sea Ice services.
