Global Sea Ice Concentration (SSMIS)
Operational Near real time productIce 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 AMSR-2 global sea ice concentration product (OSI-408 series).
Identification
Acronym : GBL SICO
Product navigator reference :
EO:EUM:DAT:DMSP:OSI-401-B
OSI SAF producer : Danish Meteorological Institute
Identifier : OSI-401-d
Digital object identifier (DOI) 10.15770/EUM_SAF_OSI_NRT_2004
Acronym for EDC (APNM) : OSICOGB
License/Attribution : See at bottom
Characteristics
Processing level : L3
Satellite input : DMSP/SSMIS
Other input : NWP outputs
Temporal sampling : 1 per day
Central time : 12:00
Timeliness :
?
The timeliness is the time elapsing from the sensing time of the last contributing file to the product dissemination to users. It is similar to the latency.
5 h
Spatial coverage : Global
Spatial sampling : 10 km
Projection : Polar Stereographic
File Formats : HL FTP Server (NetCDF3), EDC (NetCDF3), EUMETCast (NetCDF3)
Characteristics & methods : Daily averaged fractional ice cover in percentage. Include uncertainty estimates.

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.
