Gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic rain gauges. Time interval is 5 minutes. See data set nl_rdr_data_rtcor_5m_tar/1.0 for an archive that goes back to 2018. Starting with data from 31 January 2023 - 10.45 UTC onwards, this dataset is created using improved algorithms. This includes correction for signal attenuation, correction for vertical variation of precipitation, correction for fast-moving showers and use of uncertainty information in merging data from multiple radars.

-PROVISONALLY UNVALIDATED DATA- Gridded files of daily unvalidated precipitation sum in the Netherlands measured on 100-300 locations of the voluntary network from 08:00-08:00 UT. Grids are calculated based on unvalidated data (limited number of stations) as soon as the data is available, typically around 14:00. The data has only been automatically pre-validated. The complete validated dataset is Rd1. Version 2 is based on RobuKIS source data.

Archive of gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data from 1500 m over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic rain gauges. Time interval is 5 minutes. Starting with data from 31 January 2023 - 10.45 UTC onwards, this dataset is created using improved algorithms. This includes correction for signal attenuation, correction for vertical variation of precipitation, correction for fast-moving showers and use of uncertainty information in merging data from multiple radars.

This dataset is constructed using measurements of temperature-sensors at various depths. The dataset is neither validated nor are missing values completed.

Gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data from 1500 m over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic and manual rain gauges. Time interval is 5 minutes. Starting with data from 31 January 2023 - 10.45 UTC onwards, this dataset is created using improved algorithms. This includes correction for signal attenuation, correction for vertical variation of precipitation, correction for fast-moving showers and use of uncertainty information in merging data from multiple radars.

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: http://bibliotheek.knmi.nl/knmipubTR/TR245.pdf

This dataset is constructed using measurements of temperature-and humiditysensors. The dataset also contains derived physical quantities like the wetbulbtemperature, dewpointstemperature and watervaporpressure. The dataset is neither validated nor are missing values completed.

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

This dataset is constructed using measurements of electronic barometers and PWS (Present Weather Sensors). The dataset is neither validated nor are missing values completed.

This dataset is constructed using measurements of windspeedmeters (anemometer) and winddirectionmeters (windvane). The dataset is neither validated nor are missing values completed.
