Difference Between the Integrated Water Vapor Calculated from Saastamoinen and Hopfield Models in High Elevation Area

摘要: 详细分析了在高海拔地区利用Saastamoinen和Hopfield两种模型推算水汽含量时产生差异的原因,并通过对高程不同的测站上实测数据的分析和研究,给出了Hopfield模型的修正项。

Abstract: The difference between the integrated water vapor(IWV) calculated from the Saastamoinen and Hopfield models in high elevation area is analysed.The analyses show that the IWV calculated from Saastamoinen model is good for the radiosonde data,and that Hopfield model tends to overpredict IWV in high elevation area.By analyzing and researching the real measurements in different elevation stations,the modified item of Hopfield model is given.The calculating result of Saastamoinen and Hopfield models are completely consistent.
