Copernicus Marine Service Arctic MFC: Validation of chlorophyll a

Validation based on satellite data

Validation of Copernicus Marine Arctic MFC results for chlorophyll a uses data that are derived from satellite observations of the ocean colour. These data are made available from the Copernicus Marine Ocean Color TAC as OCEANCOLOUR_GLO_BGC_L3_NRT_009_101. The production is operated by the Italian Research Council (CNR).

Bias is defined as spatial averages of model values - observed values.

Region

Validation region

The validation region is between 90°W and 90°E, and between 65°N and 85°N.

Note that at these high latitudes, there will be no or very few observations during winter (November-February), due to the polar night or conditions close to this state.

ARC-MFC PHYS/BIO (TOPAZ)

The model results are produced with the TOPAZ ocean data assimilation model system. Presently, TOPAZ is run weekly with data assimillation one week prior to the bulletin date, followed by a one-week 100 member ensemble simulation ending on the bulletin date, and finally a 10 day deterministic forecast. TOPAZ was developed and is maintained by the Nansen Center.

ARC-MFC PHYS/BIO (TOPAZ) results are now deprecated, and superceded by the Copernicus Marine product ARCTIC_ANALYSISFORECAST_BGC_002_004. Archived results from ARC-MFC PHYS/BIO can be retrieved from a thredds server.
