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.

Deze dataset bevat post-processed X-band (centrale frequentie: 9,475 GHz) weerradar gegevens gemeten met de motregen radar IDRA van TU- Delft (IRCTR). De data bevat plan-positie indicators (PPI) van specifieke differentiele fase, de differentiele backscatter fase, en de geschatte neerslag intensiteit. IDRA staat boven op de 213 m hoge meetmast in Cabauw en scant horizontaal met een vaste geringe elevatiehoek. Het bereik is 15 km met een radiele resolutie van 30 m. Daarmee geeft IDRA de horizontale verdeling van neerslag rond en boven her CESAR observatorium.
