Ground precipitation cooperative quality control method based on multi-source data

The invention discloses a ground rainfall collaborative quality control method based on multi-source data. The method comprises the following steps: S1, collecting rainfall related data observed by a quality control source; s2, introducing a rainfall quality control code, and performing quality control on the rainfall data of the to-be-inspected hydrological station by using rainfall related data observed by a quality control source; and S3, determining a quality control score of the rainfall data according to the quality control identifier of the rainfall data of which the quality control is completed, further determining a final quality control identifier, and realizing cooperative quality control of ground rainfall. According to the method, meteorological station data, satellite data and radar data are used as quality control sources for cooperative command and control, and the defect of a single quality control source is effectively overcome. Quality control can be well carried out on the rainfall data of
