Precipitation - radar 5 minute echo top height composites over the Netherlands
Gridded files of radar echo top heights over the Netherlands and surrounding area. Based on 15 radar scans by two radars in Herwijnen and Den Helder. Time interval is 5 minutes. See data set radar_tar_echotopheight_5min/1.0 for an archive that goes back to 2008.

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, 0.4, 0.8, 1.1, 2.0, 3.0, 4.5, 6.0, 8.0, 10.0, 12.0, 15.0, 20.0, and 25.0 degrees. These scans are used to compute echo top heights by taking the maximum height above the earth?s surface where reflectivity exceeds 7 dBZ. These two radar images are then combined to single echo top height values by taking a the maximum of the two echo top heights. The time stamp in the file name corresponds to the start time of the lowest radar scan.
