  • Degree days are determined by the effective daily mean temperature (Teff). Teff is calculated with the daily mean temperature (TG) and the daily mean windspeed (FG). Teff = TG - 2/3 * FG. Degree days = sum of the days with (max[(14 - Teff),0]).

  • KNMI-RACMO-ECEARTH datasets of bias-adjusted precipitation, temperature (daily mean/max/min) and potential evaporation for the German and Swiss part of the Rhine catchment. Time resolution: 1-hourly for precipitation and daily for temperature and potential evaporation. Aggregation into 134 subcatchments.

  • Data set contains a 16-member ensemble of multi-annual time series of wind-induced surge and astronomical tide for eight stations along the Dutch coast. 1-hourly time series are generated with the Northsea surge model WAQUA (nominal resolution 8km) driven by 3-hourly atmospheric fields of wind and pressure obtained from the climate model RCM-GCM combination RACMO-ECEARTH. The eight stations are, ordered from south-west to north-east: Vlissingen, Hoek van Holland, IJmuiden, Den Oever, Kornwerderzand, Harlingen, Lauwersoog, Delfzijl.

  • KNMI-RACMO-ECEARTH datasets of bias-adjusted precipitation, temperature (daily mean/max/min) and potential evaporation for the Belgian and French part of the Meuse catchment. Time resolution: 1-hourly for precipitation and daily for temperature and potential evaporation. Aggregation into 15 subcatchments.

  • Archive of wind profiles derived from radar radial velocity measurements for the radar in Herwijnen. Time interval is 5 minutes. Data have been archived in one .tar file per day.

  • KNMI-RACMO-ECEARTH datasets of bias-adjusted precipitation, temperature (daily mean/max/min) and potential evaporation for the Netherlands. Time resolution: 1-hourly for precipitation and daily for temperature and potential evaporation. Subregion (26x28 cells) of native model grid at 0.11 degree resolution.

  • Dutch Offshore Wind Atlas (DOWA) project - daily files with LES hourly-averaged wind speeds for three Dutch wind parks Dissemination of high-resolution (time: 10mins; space: 64x64m) information for Dutch OWFZs (offshore wind farm zones) is a deliverable of the DOWA project. This dataset contains daily files with hourly-averaged wind speed (and standard deviation) for OWFZs Borssele (exp006), Hollandse Kust Noord (exp101) and Hollandse Kust Zuid (exp205). More information is available on the DOWA website: www.dutchoffshorewindatlas.nl

  • An important variable to calculate local temperatures is the Sky View Factor (SVF) which is the fraction of sky visible from the ground. The SVF depends on the height of the obstacles in the surroundings of a given location. The goal is to capture small features like houses and trees throughout the Netherlands at a very high resolution. This dataset comprises the Sky View Factor of The Netherlands at 0.5 meter resolution raster based on Actual Height Model of the Netherlands (AHN2) elevation dataset.

  • This dataset contains the data used for the following paper: "Climate state dependence of precipitation variability". The following variables are available on a monthly timescale: total precipitation (TP), convective precipitation (CP), large scale precipitation (LSP), evaporation (E), poleward moisture transport (MFatmos), two-metre temperature (T2M), surface temperature (SSTK), sea level pressure (MSL) and geostrophic wind (uwind and vwind). All variables are available for five quasi equilibrium simulations of 400 years length forced with a broad range of CO2 simulations (025xco2, 05xco2, control, 2xco2, 4xco2) from 50N-90N.

  • Validated short wave and longwave in and outgoing radiation at the surface from Cabauw on a 10-minute basis. At 14-June-2022 surface radiation temperatures are added from 08-September-2011 onward.
