摘　　要：文章首先从整体上分析影响自动气象站观测的各种可能因素,并建立温度观测不确定度数学模型,然后针对自动气象站温度观测数据进行定量分析,对型号A和型号B温度传感器的A类、B类、合成标准不确定度以及扩展不确定度进行了评定。通过对自动气象站温度观测数据的不确定度评估,可以有效保证温度观测资料的可比性、准确性和一致性。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.
