Study on GPS Tropospheric Delay Model Used for Forecasting Precipitable Water Amount

TANG Pu(School of Water Resources and Environmental Engineering,Nanchang Institute of Technology,Nanchang,Jiangxi 330099)  
There is a stronger correlation between GPS tropospheric delay and precipitable water amount.The precipitable water amount of tropospheric delay can be considered as the reference of the short-term climate forecast in areas without climate data.For two tiers of different height,a new tropospheric zenith delay model was set up by using linear model and exponential model.Using the aerosphere parameters of standard exponential relation and the measured data of crustal deformation monitoring station,the precision of the model was verified.The test proved the validity of the model.
