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:

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
