In the context of further professionalization of the services, the KNMI has decided to transfer data delivery to a new, secure environment where you can retrieve your data easily and free of charge. The availability of the data is at least equal to that according to the former SLAs (Service Level Agreement).
New way of downloading
KNMI has all its (open) data products available through the (open) data catalogue: KNMI Data Platform (KDP). The data is made available via APIs and no longer via FTP. The APIs are made available via the developer portal, where an account can also be created and the corresponding keys can be requested. An additional advantage of registering is that we can contact you in the event of changes or calamities. You can also obtain the data anonymously, but then this advantage will not apply.
On January 1, 2023, delivery via FTP has stopped.
If you want more information about getting started with APIs and how to use the keys, you can look at the explanation page.
ECMWF data
The exception to the above concerns the data coming from ECMWF (European Center for Medium-Term Forecasts). ECMWF has taken over your contract (or contracts) on December 31, 2022 and manages administration and invoicing itself. As for the KNMI data, you must register at ECMWF via the following link to receive instructions.
With respect to data that do not come from KNMI or ECMWF (such as OPERA data), nothing will change for now.
