The OpenIFS Data Hub is a facility to generate initial conditions for OpenIFS forecast model experiments. It is available only to users of the IFS or the OpenIFS model.
If you are interested in ECMWF datasets or need more general information about ECMWF data please follow this link.
The OpenIFS Data Hub remains temporarily unavailable – final testing before reopening is in progress What is happening? The Data Hub is currently being migrated to the new ECMWF Data Centre in Bologna, Italy. Why is it happening? During its Pilot Phase the Data Hub was implemented on hardware at ECMWF in Shinfield Park, Reading. With the completion of the new Data Centre and the ongoing migration progess of computing services to Bologna the hardware in Reading has been switched off. As a result there is currently a service interruption of several weeks, and the ability to raise new data requests has currently been disabled until the migration is complete. Uninterrupted access is provided to data from previously generated data requests on the dashboard page until the end of November 2022. What happens next? After the completion of this migration process the OpenIFS Data Hub will reopen operating from the ECMWF Data Centre in Bologna. Note that access to initial experiment data files generated prior to the switch off will not longer be possible after November 2022. OpenIFS users will be notified here and via the openifs-announce mailing list once the OpenIFS Data Hub becomes available again. |
One of the most pressing needs OpenIFS users face is to create initial conditions to start a model experiment. Until now such initial experiment data had to be requested by contacting OpenIFS support via email.
The OpenIFS Data Hub allows OpenIFS and IFS users to produce their own initial experiment data through a web-based application that triggers an automatic data generation process on our servers. The initial data files are produced using the exact same method as if the OpenIFS team had created the data. At the end of the process the user is provided with a download web link.
The Data Hub removes therefore the need to email the OpenIFS team at ECMWF and provides one common system that is available to both ECMWF staff and external OpenIFS users everywhere. Any initial data types that are currently not yet served by the Data Hub can be requested, as before, from the OpenIFS team by emailing openifs-support@ecmwf.int.
After the initial public release of the OpenIFS Data Hub, following a pilot scheme phase, we will explore possibilities to expand this data facility with additional functionality, for instance by offering a wider range of data types or by providing access to OpenIFS training data. Feedback from users will be very important for this.
The OpenIFS Data Hub can be accessed here:
You will need an ECMWF user account to access the Data Hub.
Note: Your ECMWF login credentials are required to use the Data Hub. At this time your ECMWF username needs to be added manually to the user policy to work with the Data Hub. If you are a new user of the Data Hub and have access problems please contact openifs-support@ecmwf.int. If you have used the Data Hub before the migration to Bologna with bespoke login details, then you should now use your normal ECMWF login credentials which should already have been activated for the migrated Data Hub. You will no longer require the bespoke login details. |
After the initial user authentication you will reach the Data Hub's dashboard page which shows your data request history.
To submit a new request for initial data press the "New Request" button at the top of the page. This will open a new web page containing a data request form:
Once the data request form has been completed, the request can be submitted to the Hub by pressing the Submit button.
Once this button has been pressed, the request information is added to the queue and the data generation process can begin. The request history dashboard page is shown.
Some preliminary checking is done while entering the request data.
If the dashboard page is not shown after pressing the submit button check your input fields for any errors. |
Further consistency checks will be carried out once the request has been accepted. Note that any user choices resulting in an unworkable data requests will be identified early in the process and the user request will be aborted.
A maximum data volume of 500,000 MB is permitted for a single request. Any requests exceeding this data volume will be aborted. For reference, an initial data request at the current operational grid resolution (Tco1279L137) for a single start date with 10 days forecast length has an (uncompressed) data volume of approximately 20,000 MB.
After submitting a request the dashboard page is displayed again showing the user's request history.
On this Details Page for a selected request the following information is shown:
