Lineage 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. |
