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.
