You can retrieve a subset of gridded datasets through http and https protocol.


The main idea is download exactly what you need: you can retrieve the needed variable, the geospatial coverage, the temporal coverage.

There are two ways to access this service:

  • via GUI (through the web portal)

  • or via a machine to machine interface (script).

The advantages of this service are:

  • You minimize the volume of data transiting on the network, and the volume of data to be stored on your computer.

  • You select the different parameters of your request in a “easy to understand” way: variable can be selected via their names or standard names (from CF convention standard name table), date format is harmonized at CMEMS level (ex: 2013-02-22).

  • Information on dataset (notably the updated temporal coverage) and on the request (volume of the request), can be provided to you before running the request (via GUI or via script).

  • Security of the authentication (https, CAS authentication with a ticket).
