Sea ice concentration product on satellite swath for SSMIS and AMSR-2 instruments. The product is delivered on the native spatial sampling, and with
separate product files for SSMIS and AMSR-2. The product also includes uncertainty estimates and product quality flags.
For both SSMIS and AMSR-2 the low frequency channels (19V, 37H and 37V) are used. For the AMSR-2 also the two high frequency channels (89H and 89V) are used.

Main Diffusion Means :
HL FTP server (test) SSMIS : ftp://osisaf.met.no/archive_test/ice/conc_l2_ssmis
HL FTP server (test) AMSR : ftp://osisaf.met.no/archive_test/ice/conc_l2_amsr
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.
