Precipitation - 1 hour precipitation accumulations from climatological gauge-adjusted radar dataset for The Netherlands (2.4 km) in KNMI HDF5 format

Climatological radar rainfall dataset of 1 hour precipitation depths at a 2.4-km grid, which have been adjusted employing validated and complete rain gauge data from both KNMI rain gauge networks. This dataset is updated once a month providing data up to a few months ago.

Linage statement Climatological radar rainfall dataset of 1-h precipitation depths, which have been adjusted employing validated and complete rain gauge data from both KNMI rain gauge networks. Based on the composites of radar reflectivities from both KNMI weather radars (De Bilt at 52.103 degrees N, 5.179 degrees E and Den Helder at 52.955 degrees N, 4.79 degrees E; 1998 to January 2001 only De Bilt). The time in the file name is the time of the end of the observation. Data are available for the entire land surface of the Netherlands. Pixels have 2.4 km spatial resolution. As of 31 December 2016 0800 UTC, the processing has changed and has been made similar to the processing applied to the NL25 dataset. The radar in De Bilt stopped contributing to the composite in the course of January 2017. It was replaced by a new radar in Herwijnen. Hence, as of the end of January 2017 the composites are based on the data from both new KNMI weather radars (Den Helder at 52.955 degrees N, 4.79 degrees E and Herwijnen at 5.1381 degrees N, 51.8369 degrees E). From 31 December 2016 0800 UTC till the end of January 2017, one or two radars contribute to the composite. This dataset is also available in NetCDF4 format via KNMI Data Platform. Note that the time in the file name is always the time of the end of the observation in UTC.
