Real-time data is delivered to authorised or licensed users either directly by ECMWF or via the chosen Member or Co-operating State National Meteorological Service. This choice is specified during the ordering process.
Real-time forecast data delivery - technical set-up
Our technical team will set up the dissemination of the data based on the information you have provided in the registration form that you completed when you ordered your real-time data.
We will contact you via the ticket you would have open with us to let you know that the set-up is ready and that dissemination can start.

Alternatively, for SFTP, we support SSH key-based authentication. In this configurationsetup, we will provide our public SSH key, which should be added to the ~/appropriate user's list of authorized keys on your server (typically in the .ssh/authorized_keys file on your server under within the target user account's home directory). Once installedconfigured, we will initiate connections using the corresponding private key. Please note that for ftp we support the following ports: For sftp we support: |
Our dissemination system is built in such a way that we push files. When we disseminate data from our data store, we are not only pushing objects. We are also checking if an existing object is not there already and if it is the case then we will delete it. The latter is, for example, necessary if a previous file was corrupted and we need to resend it. This means that we need permissions to rename and overwrite files we put into the receiving directory.
During the transmission, dissemination files have the extension '.tmp'. If the transmission is unsuccessful for whatever reason, it is repeated. The file gets renamed to its original name only after successful transmission.

Access to ECPDS
On 31 March 2023, ECMWF retired the ActivIdentity (HID) Security Tokens that have been used to provide a two-factor (strong) authentication access to ECMWF systems since 2007, and has replaced these with a TOTP (Time-based One-Time Password) Client application.
To access ECPDS you will need to configure TOTP.
