  • 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]).

  • 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.

  • Dutch weather warnings from KNMI. Current information about weather warnings in the Netherlands in respect to conditions of iciness and snow, rain, visibility, thunderstorm, gusts, heat stress, wind/water spouts. The warnings are issued up to 48 hours in advance. The data is published in two different formats: txt and xml.

  • Monthly mean ozone fields of the MSR. The MSR dataset results from a 30-year data assimilation run with 14 corrected satellite datasets as input, and is available on a grid of 1× 1 1/2° for the time period (1978-2008). The fourteen total ozone satellite datasets are from the instruments TOMS (on the satellites Nimbus-7 and Earth Probe), SBUV (Nimbus-7, NOAA-9, NOAA-11 and NOAA-16), GOME (ERS-2), SCIAMACHY (Envisat), OMI (EOS-Aura), and GOME-2 (Metop-A).

  • The TAF (Terminal Aerodrome Forecast) is a weather forecast for an aerodrome or airport. At KNMI, the TAF is produced for the civil airports of Amsterdam/Schiphol (EHAM), Rotterdam/The Hague Airport (EHRD), Groningen/Eelde (EHGG), Maastricht/Aachen (EHBK), Lelystad Airport (EHLE) and Bonaire International Airport (TNCB). A minimum of 4 TAFs per field are produced per day (24 hours). Minimal, because the TAF can be amended or corrected. The validity of the TAF is 30 hours. Additional information can be found in Appendix 5 on https://www.icao.int/airnavigation/IMP/Documents/Annex%203%20-%2075.pdf

  • KNMI14 daily scenario data: 2050 GL. Gridded files of daily Makkink evaporation in the Netherlands. Based on 14 automatic weather stations.

  • Daily files of wind profiles (10 minute average values) between 11 and 300m altitude, measured by the ZephIR 300M wind lidar (ZP firmware), obtained during a measurement campaign by KNMI at the Cabauw site from February 2018 to June 2020. Related datasets are <a href="https://dataplatform.knmi.nl/dataset/windlidar-cabauw-zephir300M-zp738-1s-1">windlidar_cabauw_zephir300M_zp738_1s</a> (with the raw data instead of the 10-minute averaged output), and <a href="https://dataplatform.knmi.nl/dataset/windlidar-cabauw-zephir300M-zx973-10min-1">windlidar_cabauw_zephir300M_zx973_10min</a> and <a href="https://dataplatform.knmi.nl/dataset/windlidar-cabauw-zephir300M-zx973-1s-1">windlidar_cabauw_zephir300M_zx973_1s</a>, which are wind lidar dataset that were taken with a newer firmware (ZX), for the last three months of the campaign (Feb. 2020-June 2020).

  • Gridded files of daily minimum temperature in the Netherlands. Based on 33 -35 automatic weather stations of the KNMI.
