Quantitative precipitation estimates from two Dutch C-band weather radars on a 5-min temporal and 1 km2 spatial resolution. The weather radars are operated by the Royal Netherlands Meteorological Institute (KNMI). Before 2016, the two radars were located in De Bilt and Den Helder. In the period September 2016 – January 2017, the operational radars were replaced by two dual-polarized weather radars which are located in Herwijnen and Den Helder. The time in the file name is the time of the end of the observation. Data are available within a radius of 200 km from the radar in De Bilt, which covers the entire land surface of the Netherlands. The data has undergone Doppler filtering and (since 2013) also a cloud-mask from satellite data is employed to remove non-meteorological echoes. From the volumetric reflectivity data, a reflectivity composite is constructed per radar at a constant altitude of 1500 meters. The reflectivities of both radars are then combined with a range-weighted compositing procedure. ...
