Statement

Climatological radar rainfall dataset of 5 minute 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). 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 1 km spatial resolution. 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 19 September 2016 till the end of January 2017, one, two or even three radars may contribute to the composite. Same dataset as "RAD_NL25_RAC_MFBS_5min", except that now an Extended Mask (EM) has been applied to this dataset. As a result, data are also available up to tens of kilometers away from the land surface of the Netherlands, i.e. above Belgium, Germany, and above open water. 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.
