Mercator forecasting systems


Product description

Mercator gathers data from six French institutions (CNES, CNRS, Ifremer, IRD, Meteo-France and SHOM) to create two regional (Atlantic and Mediterranean basins) and two global ocean analyses and forecasts up to 14 days. The outputs cover all four dimensions of time and space. Weekly T0 (nowcasts), T0 + 7 days, and T0 + 14 days forecasts are available in many depths for the entire globe. The products have been operational since at least 2005. Data gathered from the sources listed above includes:

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

Ocean parameters

The following parameter outputs of the Mercator system can be found here:

  • salinity
  • temperature
  • surface currents
  • sea surface height
  • mixed layer depth
  • barotropic height
  • baroclinic height
All of these products can be viewed in the weekly bulletins that are released and archived. Additionally, one can apply to access to the data through various forms (Opendap, LAS, HTTP, etc).
