Precipitation - radar/gauge 5 minute real-time accumulations over the Netherlands
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. See data set nl_rdr_data_rtcor_5m_tar/1.0 for an archive that goes back to 2018.
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.

Radar reflectivities are measured by radars in the Netherlands, Belgium, and Germany. Single images per radar at 1500 m height are generated by linearly interpolating radar reflectivities in altitude. Radar reflectivities are then converted to rainfall intensities by using the Z=200R^1.6 formula. A mean bias correction factor is derived based on the most recent 1 hour rainfall accumulations from automatic rain gauges. The resulting radar rainfall estimates from all radars are then combined to a single product by taking a weighted average. The weigths are a function of the distance of a given point to the radar.
