What's in it

Archive of gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic rain gauges. Time interval is 5 minutes.

Starting with data from 31 January 2023 - 10.45 UTC onwards, this dataset is created using improved algorithms. This includes correction for signal attenuation, correction for vertical variation of precipitation, correction for fast-moving showers and use of uncertainty information in merging data from multiple radars.

Starting with data from 18 November 2024 - 14.40 UTC onwards, this dataset is created using improved methodologies. This includes a) the usage of additional rain gauge data from water authorities and water companies, and b) reducing the quality indication of data of the Herwijnen radar of the lowest two elevations and for a small set of azimuth angles, to mitigate beam blockage due to trees and wind turbines.
