The MyOcean ARC MFC delivers ocean forecast and analysis data produced by a coupled numerical ocean-ice model with data assimilation. The products are delivered in NetCDF format via OPeNDAP and ftp from the ARC MFC data dissemination service at met.no.

From MyOcean V1, the nominal product line is based on the TOPAZ4 data assimilation system, developed by NERSC and run operationally at met.no. It produces daily mean temperature, salinity, currents, water level and sea ice fields of the Arctic Ocean, by a weekly assimilation cycle and daily updating.

Also included are products from a backup system (MIPOM Arctic20).

ARC MFC data files in NetCDF format are available from this FTP server:
