Products of CINRDA/SA are generated by radar base data directly or algorithms based on base data indirectly. Sometimes data quality goes wrong. Combing the running status information with radar base data to conduct the quality control of weather radar data is an effective approach, which can find the problems such as the abnormal values of radar echoes, no echo, and bad radar charts in time. In order to construct the stationlevel quality control method of weather radar data, the performance parameters and the monitoring and alarm information of nine weather radar sets in Jiangsu Province are analyzed, and the samples of abnormal echoes and base data are statistically analyzed and studied in detail. Based on above, the stationlevel quality control method is built, aiming to monitor the radar base data. The testing of radar base data quality is carried out. The alarm message can be sent to the duty officer immediately when it goes wrong, which is done to prevent abnormal echo data from entering the field of prediction. The prediction accuracy can be improved indirectly.
