V3 - Coriolis Analysis System


Product description

Coriolis has been running an ocean subsurface analysis system in real time since 2005. The system outputs global and Atlantic maps of subsurface temperature and salinity each week using an objective analysis method. Data is gathered from various sources including:

  • Argo floats (more than 95% of total data used)
  • CTD casts
  • XBTs
  • moorings
  • buoys
Each measurement is interpolated to a standard vertical grid. To avoid over-sampling, profiles from the same instrument within 24 hours and 24km are averaged.

Coriolis creates these products to help validate the dataset, to provide gridded temperature and salinity products for operational model validation (especially, MERCATOR), and to observe the seasonal cycle and interannual variability.

Ocean parameters

The following parameter outputs of the Coriolis Analysis System can be found here:

  • Global subsurface temperature and salinity
All of these products are in the form of maps or gridded data that can be downloaded from an LAS server.

Resolution

The gridded products are offered for either the global ocean or the Atlantic Ocean with the following resolution in each direction.

  • The resolution in longitude is 1/2 of a degree with Mercator projection.
  • The resolution in latitude is given by a Mercator projection and varies with latitude up to 1/2 a degree.
  • The vertical resolution is 5 / 10:10:60 / 80:20:320 / 360:40:1600 / 1650:50:1950

Global gridded salinity at 300m
