Precipitation - radar/gauge 5 minute final reanalysis accumulations over the Netherlands
Gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data from 1500 m over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic and manual 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.

- Statement
-
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. The resulting image is corrected by validated daily rainfall accumulations from a manual rain gauge network, using Barnes' Objective Analysis.
