Unvalidated meteorological profile observations of wind speed, wind direction, temperature, dew point and visibility from the 200m Cabauw tower on a 10-minute basis. The data is updated in realtime, so the file of the current day is updated every 10 minutes. For more information about how to interpret the data, please read: https://cdn.knmi.nl/knmi/pdf/bibliotheek/knmipubTR/TR384.pdf.

Four cloud cover parameters are retrieved continuously from sky temperature measurements by a scanning infrared radiometer (NubiScope). These parameters are resp. total, low -, middle - and high level cloud cover. Only measurements 20 degrees above horizon are used to create a hemispherical cloud mask. The temperature deviation of a sky pixel from an estimated background sky temperature determines…

Dataset containing hourly data files provided by Ruisdael Observatory's Metek Micro Rain Radar (SN 0510056436) placed at The Green Village (Van Den Broekweg 4, 2628 CR Delft). Time interval of measurements is 10 seconds and the range resolution is preferred to be set to 35 meters; however, data between 2020-11-09 and 2021-11-06 presents a 25m resolution. Compared with version 1, data will Drop Siz…

Instrumental observations of the weather have been regularly performed in the Netherlands since the end of the 17th century. An inventory was made of this period before 1854 at KNMI. The observations of the series available here appeared to have been carried out sufficiently regularly and long enough in succession.

This dataset contains the number of earthquakes, incident-parameters and trend-parameters from the earthquakes in the KNMI catalogue that took place on the Groningen gas field. The number of earthquakes are categorized by year and magnitude. The incident-parameters are the maximum PGA and PGV values of the last earthquake with magnitude >= 2.0 processed by KNMI's RRSM system. The trend-parameters …

Renewable energy is energy from wind, hydro power, the sun, the earth, biomass and heat from outdoor air. This is energy from natural processes that is replenished constantly. This table expresses the use of renewable energy in three ways: Gross final consumption Avoided use of fossil energy Avoided emissions of carbon dioxide Figures are presented in an absolute way, as wel as related t…
