Abstract In order to discuss the accuracy of temperature sensor measurement in automatic weather stations,the verification data of four types of temperature sensors in Sichuan automatic weather stations in 2019 are statistically analyzed.The data sources of WPZ,HYA-T,HYA-T-H and HMP155 sensors are introduced in detail.At the same time,the sample data are statistically analyzed from the three characteristics of pass rate,error distribution and the mean value of absolute error.And the conclusion is drawn,which is expected to provide a basis for sensor selection and evaluation of automatic weather station.
