Design and implementation of covering software in automatic meteorological station quality control system

Precipitation data quality of regional automatic weather stations determines the missed alarm and false probability of weather warning,but it is difficult to verify the validity of the data by only relying on space and time correlation of automatic data.Precipitation of weather radar can verify automatic weather station data.However,it is difficult to determine the coverage of weather stations by radar station due to heterogeneous and complex geographical environment of radar station,which results in constant error-checking.This paper built a coverage matching algorithm of radar stations and automatic weather stations by using the layer volume scan mode and the radar beam occlusion model of weather radar.Automatic stations and radar stations matching software based on the algorithm can effectively support Automatic Weather Station(AWS) precipitation data inspection.
