New service endpoint

A selection of the CAMS European air quality ensemble surface forecast layers from the new WMS server (apps.ecmwf.int) can be found here:

https://apps.ecmwf.int/wms/?token=public&request=GetCapabilities&version=1.3.0

Layer names

European air quality forecast layers are named as:

composition_europe_<VARIABLE>_forecast_surface

The table lists the available layers and the corresponding legacy layer names:

A few points:

  • based on usage statistics initially only hourly ensemble surface forecast fields are available
  • to ease the migration, legacy layer names are encoded in a layer metadata of the GetCapabilities response as "legacy name: OLD_NAME" keyword
  • the default styles and the style names are the same as before the migration


  • No labels
