Abstract Firstly,this paper analyzes the possible factors affecting the observation of automatic weather station,and establishes the mathematical model of temperature observation uncertainty on the whole.Then,quantitative analysis is made on the temperature observation data of automatic weather station.The type A,type B and combined standard uncertainty and expanded uncertainty for models A and B temperature sensors are evaluated.Through the uncertainty evaluation of temperature observation data of automatic weather station,the comparability,accuracy and consistency of temperature observation data can be effectively guaranteed.
