Overview

EFAS SOS is a web API for retrieving EFAS forecasts as data. The API returns an xml file. Example api requests can be found on the SOS services's web page. Note that in order to download recent forecasts, EFAS SOS credentials are required. These can be requested from the EFAS project.

Within EFAS, four streamflow forecast products are produced:

Forcing	Type	Ensemble range	procedure
DWD ICON	deterministic		eud_lisflood
COSMO-LEPS	ensemble	1 - 20	cos_lisflood
ECMWF-HRES	deterministic		eud_lisflood
ECMWF-ENS	ensemble	1 - 50	eue_lisflood

The European Flood Awareness System(EFAS) Sensor Observation Service(SOS) import function (<importType>EfasSosServer</importType>) imports XML files from the EFAS SOS API.

...

The following is an example of an xml config for the EFAS SOS Import Module Instance
