Accuracy of ZDR data and implications to operational radar measurements

Radar-meteorological algorithms require an accuracy of differential reflectivity (ZDR) data of about 0.1 dB. In principle, a radar system can be calibrated to provide ZDR with that accuracy. However, there are several sources of bias depending e.g. on azimuth angle or time of observation. This type of bias cannot easily be accounted for by a conventional calibration.

The following sources of systematic ZDR bias are analysed:
