Gridded files of radar-derived 24 hour precipitation accumulations, corrected by rain gauge data. Radar data from 1500 m over the Netherlands and surrounding area measured are corrected by data from KNMI's 325 manual rain gauges. Time interval is 1 day, from 8 to 8 UTC. KNMI has detected measurement anomalies caused by a defect in some rain gauges for manual precipitation observation. It concerns data from the second half of 2012 until present. At this moment KNMI is assessing the extent of the problem and investigates the options to repair the defect as soon as possible.
