Meteorological numerical prediction radar-based data quality control method

The invention relates to the technical field of meteorological numerical prediction, in particular to a meteorological numerical prediction radar-based data quality control method, which comprises the steps of radar-based data preprocessing and format conversion, radar radial wind data quality control, radar reflectivity data quality control, radar radial wind data assimilation and radar reflectivity data assimilation. Compared with the prior art, the method has the advantages that a Chinese radar-based data quality control module is developed, and the quality control effect of the Chinese radar-based data quality control module is verified through an assimilation forecast test. On the basis of an original radar quality control processing program, a netCDF interface conforming to the CF international standard is developed, output netCDF data are used, and elevation images of radar reflectivity and radial wind before and after quality control can be output through a pyart toolkit. 本发明气象数值预测技术领域，具体涉及一种气象数值预测雷达基
