Regional automatic rainfall station hourly rainfall data quality control system and method
An automatic rainfall station, data quality technology, applied in the direction of rainfall/precipitation meter, radio wave measurement system, measurement device, etc., can solve the problem that forecasters have certain difficulties in extracting and judging precipitation information, and cannot achieve real-time business operations. The requirements of quality control application, without considering the lack of radar data, timeliness and other issues, to avoid the simultaneous occurrence of missed judgments and misjudgments, avoid false heavy precipitation missed judgments, and operate reliably
