Abstract 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.
