Abstract The article focuses on solving the problem of erroneous data in station level radar operations.It statistically analyzes the erroneous data corresponding to abnormal echoes and air echoes caused by electromagnetic interference,ground interference,system failures,etc.at the Nanchong National Weather Radar Station from 2020 to 2023,and summarizes a set of methods for exploring station level weather radar data quality control based on monitoring changes in ground echoes.Develop a radar standard format data visualization platform that can quickly identify ground clutter,system abnormal echoes,and co frequency interference echoes through quality control algorithms and provide timely SMS alerts.Facilitating timely detection of problems by radar business personnel,controlling and reducing erroneous data from the source,thereby improving the stable operation rate and radar data quality of the new generation of weather radar equipment.
