Abstract:
Based on the clutter suppression principles of WSR-88D and Jinan CINRAD/SA radar detection data,an analysis is made of the temporal and spatial distribution characteristics of Anomalous Propagation(AP) echoes and the impact of AP echoes on the base data estimates and the derived products.The adaptable parameter settings of clutter suppression,which includes editing Suppression Regions and Operator Sel Code and Channel Width,when weather conditions changed are recommended.It is indicated that the appropriate application of clutter suppression regions can significantly improve the quality of the base data and all downstream products.The high level suppression can be invoked in the clear-air mode. The medium level suppression can be invoked when stratiform cloud precipitation regions are contaminated.The medium level suppression in the Doppler channel and high level suppression in the Surveillance channel can be invoked when convective precipitation cells are contaminated.
