Regional automatic station data station level quality control method
In order to do a good job in the quality control of automatic station data at the station level,this article analyzes effective methods and localization thresholds from the aspects of extreme values,maximum allowable change values,spatial consistency,and element correlation.Through example analysis,Madsen-Allerup spatial consistency check,standard deviation comparison method,and linear regression estimation method have all performed well.Business personnel can conduct grading checks according to the specific situation of the station.In the quality control of precipitation,in addition to common methods,a judgment method combining radar reflectivity and precipitation threshold is also provided to reduce misjudgments.It is hoped that the research results can provide reference for the quality control of regional automatic station data.
