摘　　要：为了确保各区域自动气象站气压传感器核查数据的可靠性,减少外界因素对核查结果的影响,文章依据现场核查的数据资料,采用理论分析和实验数据对比的方式验证核查方法的可行性,进而找出核查过程中影响气压数值变化的主要因素。实验结果表明:在区域自动气象站气压传感器的核查工作中,发现环境的温度和湿度对校准结果的最大误差有不同程度的影响,气温是主要影响因素;湿度对核查的影响较小,是次要因素。现场核查时,应选择与上一次核查环境温度差异较小的晴朗天气进行,减少误差,提高核查数据的可靠性。In order to ensure the reliability of the pressure sensor verification data of automatic meteorological stations in various regions and reduce the influence of external factors on the verification results,this article uses theoretical analysis and experimental data comparison based on on site verification data to verify the feasibility of the verification method,and then identifies the main factors that affect the changes in pressure values during the verification process.The experimental results show that in the verification work of pressure sensors at regional automatic weather station,it was found that the temperature and humidity of the environment have varying degrees of influence on the maximum error of calibration results,with temperature being the main influencing factor.Humidity has a minor impact on verification and is a secondary factor.During on site verification,it is advisable to choose sunny weather with a smaller temperature difference from the previous verification to reduce errors and improve the reliability of the verification data.
