Evaluation on data quality of CINRAD/SAD dual polarization radar in Bazhong
摘要
Abstract
In order to analyze the data quality of CINRAD/SAD new generation weather radar in Bazhong,this paper analyzes the mean and standard deviation of ground echo intensity of Bazhong radar base data from January to December in 2022,the frequency of same frequency electromagnetic interference echo and the standard deviation distribution of horizontal polarization reflectivity factor,differential reflectivity,differential phase shift and correlation coefficient by standard deviation analysis.The base data quality results of Bazhong radar are obtained.The quality stability of Bazhong radar data is high,and the mean and standard deviation of ground echo intensity change is little.There are many cases of co-frequency electromagnetic interference in Bazhong radar.In 2022,the minimum frequency of interference is May and the maximum is September.The horizontal polarization reflectance factor and differential phase shift of Bazhong radar have great fluctuation,and the quality of the differential reflectance and phase relation data is better.关键词
