Level 2 PMW Sea-Ice Concentration

Operational Near real time product

Sea ice concentration product on satellite swath for the AMSR3 instrument. The product is delivered on the native spatial sampling. The product also includes uncertainty estimates and product quality flags. The low frequency channels (19V, 37H and 37V) and the two high frequency channels (89H and 89V) are used.

Accuracy Requirements
Target accuracy : 10 % for NH-product. 15 % for SH-product
Verification/validation method : Comparison with high resolution manual ice charts (Frequency of availability between once a day and once a week): the performance shall be validated for only the “ice” (100 % ice) and “water” (0 % ice) cases, separately.
Applications and users
Usage : NWP and Ocean/Ice models, operational Met and Sea Ice services.
