  • Validated surface fluxes of net radiation, momentum, sensible heat, latent heat, soil heat and carbon dioxide at Cabauw on a 10-minute basis. For more information about how to interpret the data, please read: https://cdn.knmi.nl/knmi/pdf/bibliotheek/knmipubTR/TR384.pdf. Please note: Due to dataset maintenance, data uploading has been halted temporarily since 01-06-2021 for an unspecified time.

  • Groundwater levels at Cabauw have been measured since August 2003 in two fields south of the tower. Nine piezometers were placed in a row. Initially, 6 of those piezometers contained pressure transducers (of the brand Keller) to measure levels automatically every 4 hours. On 9 July 2010, the temporal resolution was increased to hourly. Several sensors have stopped working since 2003. Piezometers that were not measured automatically were measured during each filed visit, which was initially every 2 weeks, but has become longer towards the end of the measurement period.

  • Discharge has been measured at three locations. At these locations, measurement weirs have been installed in May 2007 to estimate discharges accurately. A V-notch weir is used to measure the inflow of surface water into the catchment near the Wielse Kade (Qin). Trapezoidal Rossum weirs have been installed to measure outflow (Qout1 and Qout2), of which the stage-discharge relations have been obtained by laboratory calibration. The uncertainty associated with the discharge measurement can be considerable in some cases.

  • North Sea wind profiles with 10 minute averages measured by the ZephIR 300M wind lidar. Data are daily files reported by the instrument. Locations are the TenneT platforms BSA, BSB, HKZA, HKZB, HKN, HKWA (operational starting 2019-2023), located within the wind farms BS, HKZ, HKN, and HKW.

  • This dataset contains particulate matter mass concentration measurements using a TEOM 1400a sensor unit in combination with Series8500 FDMS monitor. The instrument is located in a Portakabin 500m north from the Cabauw tower.

  • Dutch Offshore Wind Atlas (DOWA) project - LES-time series at locations in Dutch offshore 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 time series with 10 minute averaged wind speed, wind direction, air pressure, relative humidity and temperature from Whiffle's Large Eddie Simulation model GRASP using tendencies constructed from the ECMWF reanalysis ERA5. Wind parks have been included in the LES model for the periods they have been operational. The files with *_fs_* in the file name contain free-stream fields, i.e. without wind parks. The time series contain values at heights from 10 to ca. 600m. The attribute experiment in the NetCDF files indicates the wind park: Borssele (006), Hollandse Kust Noord (101) or Hollandse Kust Zuid (205). More information is available on the DOWA website: www.dutchoffshorewindatlas.nl

  • 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.
