To enhance the application value of precipitation observation data in public meteorological services, this study investigates a quality control method for precipitation data based on multi-source meteorological data and machine learning models. Based on the meteorological station data, multi-source integrated analysis products, meteorological radar, and satellite products, as well as the XGBoost model, a multi-source collaborative quality control method for precipitation data was developd by comprehensive scoring. The accuracy of this method was evaluated using the artificial error implantation technique. The results indicate that when random precipitation anomalies are implanted, the detection rate of erroneous data is 0.85; When errors are implanted at different precipitation levels, the detection rate of erroneous data is 0.79. After collaborative quality control, the average error between the precipitation data to be tested and neighboring meteorological stations is reduced by 15%, and the correlation coefficient is increased to 0.7-1.0. Therefore, this method can effectively identify suspicious precipitation data, which can provide strong data support for meteorological disaster prevention and mitigation.
