Description

This dataset contains post-processed X-band (central frequency of 9.475 GHz) weather radar data from the TU Delft IRCTR drizzle radar IDRA. It includes plan-position indicators (PPI) of the specific differential phase, the differential backscatter phase, and the estimated rainfall rate. IDRA is mounted at the top of the Cabauw tower at 213 m agl., and is scanning horizontally at a fixed low elevation angle, covering a slant range of 15 km with a range resolution of 30 m. IDRA thus provides the horizontally spatial distribution of precipitation over the CESAR observatory.
