  • 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 (www.nodc.nl), 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.

  • Volumetric soil moisture contents have been measured daily between 6 november 2003 and 19 August 2010 with a TDR set-up developed by Heimovaara and Bouten consisting of six arrays of six sensors between 5 and 73 cm below the soil surface. The six arrays were positioned on the perimeter of a circle with a diameter of 9 m with equal distances. The TDR was calibrated by taking 6 undisturbed soil samples (diameter: 20 cm; height: 20 cm) into the lab and comparing independently measured volumetric soil moisture contents to the TDR measurements. Measurements were performed at midnight local time, without taking daylight savings time into account.

  • Dataset containing hourly data files provided by Ruisdael Observatory's Metek Micro Rain Radar (SN 0513108314) placed at Westmaas. Time interval of measurements is 10 seconds and the range resolution is preferred to be set to 35 meters.

  • Global monthly precipitation from 1970 to 2100 per land grid cell. The data is licensed under CC-BY. The IMAGE-team would appreciate to be involved in projects using the data. SSP scenarios are documented in: Energy, land-use and greenhouse gas emissions trajectories under a green growth paradigm, https://doi.org/10.1016/j.gloenvcha.2016.05.008

  • Dataset containing hourly data files provided by Ruisdael Observatory's Metek Micro Rain Radar (SN 0510056436) placed at The Green Village (Van Den Broekweg 4, 2628 CR Delft). Time interval of measurements is 10 seconds and the range resolution is preferred to be set to 35 meters; however, data between 2020-11-09 and 2021-11-06 presents a 25m resolution. Compared with version 1, data will Drop Size Distribution spectra variable, as the instrument's firmware has been update to a newer version (v2.0.23). Notes: Being The Green Village a test site, there could be some effect on the quality and availability of the data.

  • The European climatological gauge-adjusted radar precipitation dataset, EURADCLIM, addresses the need for an accurate (sub-)daily precipitation product covering 8000000 square kilometers of Europe at high spatial resolution. It consists of 1-h and 24-h precipitation accumulations (every clock-hour) at a 2-km grid for the period 2013 through 2020. It is based on the European Meteorological Network (EUMETNET) Operational Program on the Exchange of weather RAdar Information (OPERA) gridded radar dataset of 15-min instantaneous surface rain rates. For EURADCLIM, first methods have been applied to further remove non-meteorological echoes from these images by applying two statistical methods and a satellite-based cloud type mask. Second, the radar composites are merged with the rain gauge data from the European Climate Assessment & Dataset (ECA&D) in order to substantially improve its quality. We expect to rerun EURADCLIM once a year over the entire period, using all available ECA&D rain gauge data, and extend it with one year of data. This will result in a new version of this dataset.

  • This dataset contains the location (epicentre), origin time (UTC), magnitude, depth [km] and type of all the earthquakes in and around the Netherlands. The location of the epicentre has an uncertainty of approx. 1 kilometer (horizontal). The type of earthquake distinguishes between natural (tectonic) earthquakes and induced earthquakes. The seismic network of the KNMI consists of geophones in boreholes (up to 300 m depth), accelerometers, and "broadband" seismometers.

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

  • This dataset represents AOD (Aerosol Optical Depth) estimates, retrieved from LARISSA (Lidar Aerosol Retrieval based on Information from Sea Surface of Aeolus)

  • Current operational HARMONIE information in gridded form (regular lat-lon) of weather parameters from the KNMI HARMONIE-AROME Cy40 model. The output frequency is 1 hour. For more details and explanation of GRIB codes in HARMONIE, follow this link (NL): https://www.knmidata.nl/open-data/harmonie.
