  • Gridded files of the 24 hour summary of probability of hail from radar over the Netherlands and surrounding area. Based on 14 radar scans by two radars in Herwijnen and Den Helder. Time interval is 5 minutes.

  • Gridded files of daily precipitation sum in the Netherlands measured on +- 300 locations of the voluntary network from 08:00-08:00 UT. Grids are calculated based on validated data with a 4 week delay on average.

  • Archive of gridded files of probability of hail from radar over the Netherlands and surrounding area. Based on 14 radar scans by two radars in Herwijnen and Den Helder. Time interval is 5 minutes. Data have been archived in one .tar file per day.

  • A ground-based UV-polarisation lidar was deployed to infer cloud droplet sizes and droplet number concentrations near the cloud base of cumulus clouds over Ascension Island. The measurements were part of the 2016 en 2017 ASCII campaigns to study aerosol-cloud interactions in the stratocumulus to cumulus transition zone of the southeast Atlantic Ocean. Measurements of uncalibrated attenuated backscatter were acquired at 30 seconds and 15 meters resolution.

  • -PROVISONALLY UNVALIDATED DATA- Gridded files of daily unvalidated precipitation sum in the Netherlands measured on 100-300 locations of the voluntary network from 08:00-08:00 UT. Grids are calculated based on unvalidated data (limited number of stations) as soon as the data is available, typically around 14:00. The data has only been automatically pre-validated. The complete validated dataset is Rd1. Version 2 of this dataset is available with start date January 1st 2018.

  • KNMI collects observations from the automatic weather stations situated in the Netherlands and BES islands on locations such as aerodromes, North Sea platforms and wind poles. This dataset provides metadata on these weather stations, such as location, name and type. The data in this dataset is formatted as CSV. It is also available as a NetCDF file in this dataset: https://dataplatform.knmi.nl/dataset/waarneemstations-5.

  • Sonic anemometer observations from the two RWS stations FL47 and FL48 at Lake IJssel, derived from 50 Hz resampled data

  • The European climatological gauge-adjusted radar precipitation dataset, EURADCLIM, addresses the need for an accurate (sub-)daily precipitation product covering 8000000 square kilometers of Europe at high spatial resolution. It consists of 1-h and 24-h precipitation accumulations (every clock-hour) at a 2-km grid for the period 2013 through 2020. It is based on the European Meteorological Network (EUMETNET) Operational Program on the Exchange of weather RAdar Information (OPERA) gridded radar dataset of 15-min instantaneous surface rain rates. For EURADCLIM, first methods have been applied to further remove non-meteorological echoes from these images by applying two statistical methods and a satellite-based cloud type mask. Second, the radar composites are merged with the rain gauge data from the European Climate Assessment & Dataset (ECA&D) in order to substantially improve its quality. We expect to rerun EURADCLIM once a year over the entire period, using all available ECA&D rain gauge data, and extend it with one year of data. This will result in a new version of this dataset.
