The THREDDS Data Server (TDS) is a web server that provides metadata and data access for scientific datasets, using different services such as OPeNDAP, WMS, FileServer and other remote data access protocols. 

The OPeNDAP service

OPeNDAP handles transport, translation and subsetting of data. OPeNDAP allows you to access remote data over the internet:

  • using familiar data analysis and visualization packages like Matlab, Ferret, IDL,... as if the data were on your computer
  • without worrying about data storage formats, translating them on-the-flight (including in ascii), if necessary
  • accessing only the data of interest (extracting geographical area, time series...).

The WMS (Web Map Service)

WMS is is a standard protocol for serving georeferenced map images over the Internet. These images are typically produced by a map server from data provided by a GIS database.

The FileServer Service

Enables to download a set of files 

The NetCdfSubset Service

Enables to extract a data sub-set from the Aviso gridded datasets. You can choose either an area (by its geographical coordinates or among pre-defined regions), or a period for variable(s) within a given dataset.
