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.

Required information for delivery of real-time forecast data from ECMWF

We deliver real-time products via ftp, sftp, AmazonS3, Microsoft Azure and Google Cloud. Please click on one of the options below to see the exact requirements for all these methods. 

 We will need the following information:
  • host name or IP
  • protocol (ftp/sftp)
  • username and password with permission to read-write and rename
  • receiving directory

Please note that for ftp we support the following ports:
21 (standard)
2121 (non standard)

For sftp we support:
22 (standard)
2222 (non standard)

FTP/SFTP

We will need the following information:

  • aws_access_key_id 
  • aws_secret_access_key
  • Bucket name

We will need the following information:

  • SAS (SharedAccessSignature) URL

  • Blob container name

For Google Cloud Platform, we are using the s3 API to access your account. We will need the following information:

  • aws_access_key_id 
  • aws_secret_access_key
  • Bucket name


Our dissemination system is built in such a way that we push files. We need permission 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.
