KNMI Data can be downloaded via the KNMI Data platform. Most of the data you will find here is freely available. In addition to KNMI datasets, KNMI can also provide advice and services in making meteorological data available from and on behalf of European Meteorological organizations.
Within KNMI Data Platform you can search in the catalog for specific datasets. Here you can find the metadata of a dataset and more information on access to the dataset via the API (Application Programming Interface). The Developer Portal provides further explanation on how to download data with our APIs and how to get started.
Open Data
Making open data available for reuse refers to actively making data available as free downloadable files. Services around free downloadable datasets are kept limited from a cost perspective. The download capability and capacity for making open data available is limited to a best-efforts obligation regarding availability and timeliness. With open data, no services are provided such as technical support or security of data delivery. The provision of these open data takes place in accordance with the CC BY 4.0 Creative Commons license, which means, among other things, that the user of the data must state that they originate from KNMI.
Reuse of government information
This is reuse as referred to in the law of reuse of government information (Dutch) as far as intellectual property rights of others do not restrict it, whereby additional services can be provided on the basis of an agreement.
Market and government
The relationships between market and government are regulated, among other things, by the Competition law. When it comes to making operational, weather related products and services available outside the government, the policy principle is that the existing market conditions are not affected.
What products and services are provided in the field of weather is largely determined by the demand of clients or buyers. Of course within the legal framework. KNMI's statutory tasks include, for example, scientific research (into geophysical phenomena such as weather, climate, seismology and space weather and their impact on society), general weather reports, weather warnings, information about earthquakes, the national climate scenarios and maintaining the national monitoring network.
