Measurement uncertainty and system assessment of weather radar network in Germany

The Deutscher Wetterdienst (D WD) weather radar network has been upgraded with new C-band Polarimetrie radar systems. The current study presents the results of a field research campaign, which was designed to assess the radar systems through analyzing radar measurements. A novel point mode approach proposed recently by Enterprise Electronics Corporation (EEC) was used for the data collection and analysis. Results show that DWD weather radars generally have a high system quality and contribute a negligible uncertainty to the radar measurements, as compared to the uncertainty caused by the sampling effect. The proposed point mode approach is validated with DWD radar data analysis and highly recommended as quality measure for commercial weather radars.
