GPS Precipitable Water Vapor of Different Climate Types

From the GPS data of crustal movement observation network of China(CMONOC) from 2000 to 2004,the precipitable water vapor time series of all stations are obtained.According to the different climate types,the GPS stations of CMONOC are clarified.During the comparison of precipitable water vapor among different climate types,the values of precipitable water vapor in different regions were arranged from lowest to highest.These regions are of alpine climate,temperate continental climate,temperate monsoon climate,sub-tropical monsoon climate and tropical monsoon climate.The results show that the waveform changes of precipitable water vapor of different climate types are different.
