Which way to access data
The EFAS archive contains the operational output of EFAS as well as the historical simulations. The real-time EFAS forecasts are restricted to the EFAS partners, all data that is older than 30 days is open access. For more information of the model setup, please see the EFAS overview. The data download facilities provide access to the raw hydrological model output; the different ways to access the data are designed to help different usage. For more information on EFAS archive data and its accessibility, please see the EFAS archive wiki pages.
Copernicus Climate Data Store
The CDS is an easy-access archive for all kinds of climate-related data. Retrieving relevant information and manipulation of the data can be done through the toolbox. It is available openly to the general public.
The CDS is the recommended and easiest way to access EFAS data and all relevant metadata information; users can select the type of data and dates of the time series they want to download. All archived EFAS data is in the form of raw hydrological time series outputs, and accessible to all. All versions of EFAS from v2 for historical and v4 for reforecasts are available for download. The data is currently available as GRIB2 or NetCDF.
ACCESS: The data is available for anyone to use under a Copernicus data license. Please follow the links below to get to the data.
| Type | Dataset | Start date | End date |
|---|---|---|---|
| Forecasts | EFAS forecasts | 2018-10-18 | Continuing in near real time |
| EFAS seasonal forecasts | 1991-01-01 | Continuing in near real time | |
| Reforecasts | EFAS reforecasts | 1999-01-03 | 2018-12-30 |
| EFAS seasonal reforecasts | 1991-01-01 | 2020-10-01 | |
| Historical run forced with observations | EFAS historical simulations | 1991-01-01 | Continuing in near real time |
Meteorological Archival and Retrieval System (MARS)
MARS is the main repository of meteorological data at ECMWF. It contains petabytes of operational and research data, as well as data from Special Projects. Access to the MARS archive requires an account with ECMWF. Read the MARS documentation for more information.
Users can browse the Archive catalogue (describing archive data that ECMWF can distribute) or the complete MARS catalogue (authorization required) from dedicated server. Users can select which part of the data that they would like to download in terms of area, dates, forcing model, time step, variables etc. Whilst the MARS archive offers a huge flexibility for download, it requires some basic programming skills to retrieve the data and might not be suitable to all. Please see the wiki page on MARS for more information.
ACCESS: If you are a registered user of ECMWF products, you will find the Copernicus EFAS data here: https://apps.ecmwf.int/mars-catalogue/
To create an account, please log a request through the ECMWF Support Portal.
Access to real-time forecast
EFAS partners who have access to the real-time information on the EFAS-IS map viewer can also have direct access to the forecast data through a password protected ftp. This enables the users to get a sub-sample of the operational data as a direct ftp transfer. The operational data are saved for 30 days on the ftp then moved automatically to the MARS and CDS archives.
ACCESS: Please see the wiki page on access to EFAS data through ftp for more information
