摘　　要：自动气象站气压传感器检定规程规定的实验室检定环境温度的要求与其在观测场的环境温度差异较大,为此,文中研究环境温度对自动气象站气压传感器测量误差的影响。选取国内常用的PTB210型、PTB220型和DYC1型各8只气压传感器,置于-40~40℃之间的9个整10℃点的环境温度下,分别对各传感器500~1100 hPa之间的7个整100 hPa点进行性能测试,并对测量数据进行定量分析。结果表明:PTB210型、PTB220型和DYC1型气压传感器的测量误差平均值均随环境温度的变化而变化,PTB210型和DYC1型气压传感器的测量结果受环境温度的影响较大,而PTB220型气压传感器的测量结果受环境温度的影响较小。The requirements for laboratory verification of ambient temperature specified in the verification regulations for atmospheric pressure sensors at automatic weather stations differ greatly from the ambient temperature at the observation site.Therefore,the impact of ambient temperature on the measurement error of atmospheric pressure sensors at automatic weather stations is studied.Eight air pressure sensors of PTB210,PTB220 and DYC1 commonly used in China are selected respectively,and placed at 9 points between-40℃and 40℃in ambient temperature at the interval of 10℃.The performance of each sensor was tested at 7 points between 500 hPa and 1100 hPa at the interval of 100 hPa.The measured data are analyzed quantitatively.The results show that the average measurement error values of PTB210,PTB220 and DYC1 pressure sensors vary with the change of ambient temperature,and the measurement results of the PTB210 and DYC1 pressure sensors are greatly affected by the ambient temperature,while the measurement results of the PTB220 pressure sensor are less affected by the ambient temperature.
