Registered EFAS users with access to EFAS real-time information can access real-time EFAS hydrological forecasts through the ECMWF 's production Production Data Store (ECPDS). The data (hydrological time series for each ensemble member for the entire EFAS domain) is stored as one grib file per forecast with the naming convention of foreacstdate.grb / YYYYMMDDTT.grb, for example, "2019040300.grb" for forecast produced the 3rd of April 2019 using 00UTC meteorological forecast forcing. All forecast time steps (i.e. from day one to day 10) are within the same file for easier access.
The data is restricted to authorised EFAS users and is password protected. User ID is the first part of your email before the '@' address; your password will be provided by email after registration to the service. To subscribe, please send a request to efas@ecmwf.int.

After logging in, available data is shown as a list of files in the browser. The data is split into the file with all the forecasts forecasts in one file ("EFAS_forecasts_YYYYMMDDHH.grb") and the simulation forced with observations in a separate file ("EFAS_sfo_YYYYMMDDHH.grb).

Automatic download is done by clicking on a file name. As each file is large, due to the amount of archived information they contain, download downloads can be slow. Once downloaded, access to the data can be made directly from the GRIB file, or after conversion as to netCDF.
Automatic data transfer
In addition to manual download, an automatic data transfer is also possible, where data is sent to the service subscriber as soon as it is available. If you are interested by in such a service, please send an email to efas@ecmwf.int.

Access to real-time river flow forecasts and reforecasts from GloFAS (both GloFAS 30-days and GloFAS Seasonal) is possible through a dedicated ftp service set-up by the GloFAS team upon request. Data is provided either as point time series or 2D grid series, both in netCDF format.
Request of A request for real-time forecasts or , forecast reruns, or any other inquiry and feedback on the service can be made using the contact us page on the GloFAS website. The team endeavours to respond to all requests as soon as possible within 15 working days. Please provide the following information when sending a request for data, including the period of simulation requested (real-time or forecast reruns):
- Requesting data for stations/points (only for river sections with upstream area larger than 1000 km2):
- Station ID(s)
- Name of station(s)
- Name of Riverriver(s)
- Name of country
- Station latitude(s)/longitude(s)
- Station upstream area(s) from provider (if available)
- Requesting data for areas:
- Latitudes/longitudes of the bounding box region
...
This data stream will mirror the existing data stream and will be stored on the FTP under the version number of the GloFAS release.
All files will use an identical folder structure to the previous release.
