  • Encoded, synoptical in-situ observations per one hour of all parameters derived from the available operational stations in the Netherlands and the Dutch part of the North Sea continental shelf in the format of the WMO code form FM94 BUFR.

  • The KNW (KNMI North Sea Wind) atlas is based on the ERA-Interim reanalyses dataset which captures more than 40 years (January 1979 - August 2019) of meteorological measurements and generates 3D wind (temperature, etc) fields consistent with these measurements and the laws of physics. Read the manual at the KNW website: https://www.knmiprojects.nl/projects/knw-atlas. This dataset is downscaled using the state-of-the-art weather forecasting model, HARMONIE with a horizontal grid of 2.5 km. The vertical profile of wind speed was calibrated against the 200 m tall Cabauw measurement mast to obtain a single wind shear correction coefficient which was applied throughout the whole dataset. The result is a high resolution dataset of more than 40 years: the KNW dataset. The model statistics in this specific dataset cover the original 35 year period of the KNW Atlas.

  • Transformed daily time series for maximum temperature for the KNMI'14 scenarios for around 2030, 2050 and 2085 for 14 stations in the Netherlands (revised 2015). Can also be downloaded through http://www.klimaatscenarios.nl/toekomstig_weer/transformatie/index.html

  • ransformed daily time series for precipitation for the KNMI'14 scenarios for around 2030, 2050 and 2085, subscenario Lower, for 240 stations in the Netherlands (revised 2015). Can also be downloaded through http://www.klimaatscenarios.nl/toekomstig_weer/transformatie/index.html

  • Pre-controlled data of the 24 hour (08-08 UTC) precipitation amount from 322 stations in the KNMI climatological precipitation network (situation per 01-Jan-2018).

  • Archive of gridded files of radar-derived 3 hour precipitation accumulations, corrected by rain gauge data. Radar data from 1500 m over the Netherlands and surrounding area measured are corrected by data from the 32 KNMI automatic rain gauges. Time interval is 1 hour. Data have been archived in one .tar file per day.

  • Historic gridded files of daily precipitation sum in the Netherlands from 1910-2010 measured on 102 homogenized observations of the voluntary network. The time interval is 08:00-08:00 UT.

  • Gridded files of radar reflectivities at 1500 m over the Netherlands and surrounding area measured by two radars in Herwijnen and Den Helder. Time interval is 5 minutes. See data set radar_tar_refl_composites/1.0 for an archive that goes back to 2008.
