Mercator forecasting systems

Product description

Mercator Ocean operates a 1/12° global system. There are daily forcasts and weekly analyses. In addition to the physical forecast, there is also a weekly global biogeochemical forecast at 1/4°. Finally, a higher resolution (1/36°) model covers the Iberian Biscay and it is updated daily. Data gathered from the following sources are used in the systems:

  • Sea level anomaly (SLA)
  • Sea surface temperature (SST)
  • T / S profiles (Argo profiles represent more than 50% of profiles)

Ocean parameters

The following are the parameter ouputs of the Mercator Ocean system:

  • salinity
  • temperature
  • surface currents
  • sea surface height
  • ice parameters
All of these products can be viewed in the weekly bulletins that are released and archived.

The data can be accessed through the My Ocean catalog. Enter "mercator" into the search box and several results should appear. Choose which data set you prefer by the resolution and description. To find the regional data, enter "Iberian" into the search box. The following direct links are from the My Ocean database and may not always work:
