  • This dataset is constructed using measurements of sensors for seawatertemperatures, waveperiodes and -heights. 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 is constructed using measurements of electronical raingauges and Present Weather Sensors. 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 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.

  • Current operational HARMONIE ensemble information in gridded form (regular lat-lon) of near surface and boundary layer (up to 300 m) 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.

  • -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.

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.

  • Current operational HARMONIE information in gridded form (rotated lat-lon) of near surface and boundary layer (up to 300 m) parameters and a few pressure levels 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.
