WHOS web services and supported tools

Back to WHOS

WHOS data are organized and published in different WHOS Views. WHOS Views are the data subsets defined by a given area, institution, temporal extent, and/or variable, e.g. WHOS-Arctic.

Each WHOS View can be accessed by means of various tools and applications. For this, WHOS makes available web service endpoints implementing various standard communication protocols and metadata/data models that are supported by different tools.

WHOS endpoints and examples of supported tools

To access and use all data of a specific WHOS View, users need to configure their tool, application or system with the corresponding web service endpoint selected below. In order to make the endpoints operational, users should complete them with:

  1. View Identifier (to access and use specific data subsets): 

    • whos-arctic (hydrometeorological data for the Arctic basin)

    • whos-plata (hydrometeorological data for the La Plata river basin)

    • whos (all WHOS data aggregated by data provider) 

  2. Personal Token Identifier generated after WHOS User Registration
