Precipitation - radar 5 minute reflectivity composites over the Netherlands - archive

Archive of gridded files of radar reflectivities at 1500 m over the Netherlands and surrounding area measured by two radars in Herwijnen and Den Helder. Time interval is 5 minutes. Data have been archived in one .tar file per day.

Linage statement 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. These two radar images are then combined to a single image by taking a weighted average of the radar reflectivities. The weigths are a function of the distance of a given point to the radar. The time stamp in the file name corresponds to the start time of the lowest radar scan.
