DWD Radar Products

:dwd_radar_pi_klein.png

PI international radar composite (rad_rapi)
  • international radar reflectivity (dBZ) composite
  • covers central Europe (1440 km * 1440 km)
  • 6 reflectivity classes
  • temporal resolution: 15 min
  • spatial resolution: 4 km


RY national radar composite (rad_rary)

:domain_radar.png

  • radar-derived precipitation analysis
  • only in the overlap area of different radars the QY quality information is used (to decide which radar's information is less flawed)
  • covers Germany (900 km * 900 km)
  • temporal resolution: 5 min
  • spatial resolution: 1 km
QY (radar quality product rad_raqy)
  • radar quality product containing quality flags that indicate errors and quality problems identified in the quality check
  • covers Germany (900 km * 900 km)
  • temporal resolution: 5 min
  • spatial resolution: 1 km
LMK radar product (rad_ralh)
  • national quality-checked radar precipitation analysis on LMK grid for latent heat nudging (only summer)
  • combines RY with QY information, i.e. at gridpoints where QY indicates quality problems its value is set to “error”
  • temporal resolution: 5 min
  • spatial resolution: 2.8 km
  • filename convention: lafyyyymmddhh
  • each hourly file contains 12 5-min precipitation sum records
RADOLAN (rad_rarw)
  • radar-derived precipitation analysis
  • online calibrated to ground observations to give 1-h precipitation sums
  • available (nearly) immediately
  • undefined in case of missing radar data, therefore not suitable as estimate for long-term precipitation sums
  • spatial resolution: 1 km
