ECMWF has announced that they will go fully Open-Data in October 2025 see press release
We asked ourself what does that mean in terms of spatial and temporal resolution of the different datasets?
Are they provided on their native grid and temporal resolution? E.g. the extended range forecast?
Hi Daniel,
Thanks for your query.
For ECMWF, Open means a permissive licence will apply and there will be no cost for the data itself, but delivery charges may apply.
In this case, the CC-BY-4 licence will apply to the full contents of the ECMWF Real-time Catalogue at all resolutions/time steps. The Information Cost (cost per data) will be removed, but delivery charges will still apply for bulk download, area subsetting, formatting, customisation, etc.
We hope to release a free subset at 0.1 degrees in October, but the products within this subset are yet to be confirmed.
The extended range is already ‘open’ (it has a CC-BY-4 licence) - you can access this via the S2S public dataset or if you want it directly from ECMWF, Service Charges would still apply and you’d need to submit a quote here.
Hope this helps and happy to answer any further questions!
Kind regards,
Emma
