Precipitation - radar/gauge 24 hour accumulations over the Netherlands
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.

Radar reflectivities are measured by both radars (De Bilt at 52.1017 N, 5.1783 E and Den Helder at 52.9533 N, 4.7900 E) in scans with elevation angles of 0.3, 1.1, 2.0, and 3.0 degrees. These scans are used to generate a single image per radar at 1500 m by linearly interpolating radar reflectivities in altitude. Radar reflectivities are then converted to rainfall intensities by using the Z=200R^1.6 formula, and these rainfall intensities are accumulated to 24 hour sums, from 8 to 8 UTC. The entire rainfall product is then corrected using the KNMI network of manual gauges.
