  • The National Oceanographic Data Committee (NODC) of the Netherlands is the national platform for exchange of oceanographic and marine data and information, and for advisory services in the field of ocean and marine data management. The overall objective of the NODC is to effect a major and significant improvement in the overview and access to marine and oceanographic data and data-products from government and research institutes in the Netherlands. This is not done alone and only with a national focus, but on a European scale as an active partner in the Pan-European SeaDataNet project, complying to the INSPIRE and the new Marine Strategy EU Directives, and on a global scale as the Netherlands representative in major international organisations in this field, ICES and IOC-IODE. A major step has been made with the launch of the NODCi - National Infrastructure for access to Oceanographic and Marine Data and Information. This was developed in the framework of the Ruimte voor Geo-Informatie (RGI) programme as RGI-014 project. It includes a new NODC-i portal (, that provides users with a range of metadata services and a unique interface to the data management systems of each of the NODC members. By this Common Data Index (CDI) interface, users can get harmonised access to the datasets, that are managed in a distributed way at each of the NODC members. The NODCi portal functions as the Dutch node in the SeaDataNet infrastructure. The NODC CDI service contains several thousands of references to individual marine and oceanographic datasets. For inclusion in the National Geo Register these have been aggregated by combinations of Data Holding Centres - Disciplines. Each NGR - NODC record therefore represents a large number of individual metadata records and associated datasets. By following the specified URL to the NODCi portal, users can consider these metadata in detail and can achieve downloading of interesting datasets via the shopping cart transaction system, that is integrated in the NODCi portal.

  • This dataset contains images of scanned analog seismograms for historical earthquakes. They belong to the old instrumentation of the following KNMI seismic stations in the Netherlands: De Bilt (DBN), Epen (ENN), Heerlen (HEE), Ravensbos (RSB), Witteveen (WIT) and Winterswijk (WTS). The different parts of the name of the images correspond to: station code, channel code, instrument code, time of the first minute of the seismogram, time of the end of the seismogram (approximate) and version number. The complete description of the stations, their instrumentation and the channel codes can be found in the following report:

  • This dataset is constructed using measurements of cloudheight-sensors and a algorithm for coverage. The dataset is neither validated nor are missing values completed.

  • Gridded files of average yearly minimum temperature in the Netherlands over the period 1981-2010 (normal period). Based on 28 automatic weather stations.

  • KNMI14 daily scenario data: 2050 GL. Gridded files of daily Makkink evaporation in the Netherlands. Based on 14 automatic weather stations.


  • Validated surface fluxes of net radiation, momentum, sensible heat, latent heat, soil heat and carbon dioxide at Cabauw on a 10-minute basis. For more information about how to interpret the data, please read: Please note: Due to dataset maintenance, data uploading has been halted temporarily since 01-06-2021 for an unspecified time.

  • Winds of the North Sea in 2050 (WINS50): wind speed, wind direction, temperature, pressure and relative humidity at 10-600 meter height from a reanalysis for 2019-2021 with the NWP model HARMONIE-AROME nested in the ECMWF reanalysis ERA5. Data are stored as daily files for a subdomain covering the Netherlands. More information on:

  • Frequency tables for different meteorological quantities for different KNMI measuring stations, for the period 1981-2000.

  • Validated meteorological profile observations of wind speed, wind direction, temperature, dew point and visibility from the 200m Cabauw tower on a 10-minute basis.
