Radar reflectivity - data measured with an X-band radar at 213 m height in Cabauw

This dataset contains X-band (9.475 GHz) weather radar measurements from the TU Delft IRCTR drizzle radar IDRA. It includes plan-position indicators (PPI) of co-polarised reflectivity measurements at horizontal polarisation. IDRA is mounted at the top of the Cabauw tower and is scanning horizontally at a fixed low elevation angle, covering a radius of 15 km (30 m range resolution) or 1.5 km (3 m range resolution). The antenna of IDRA is rotating at a speed of one round per minute. The dataset contains one PPI every five minutes.
