地基GPS反演大气可降水量方法的改进

Improvement on the Method for Estimating Precipitable Water from Ground-based GPS

摘要: 利用地基GPS反演大气可降水量(PW,precipitable water)的方法中,GPS PW的准确度依赖于天顶静力延迟(ZHD,zenith hydrostatic delay)的计算模型和转换系数П。分析Saastamoinen模型、Hopfield模型、Black模型计算的ZHD误差发现,其计

Abstract: In the method for estimating precipitable water(PW) from ground-based GPS,the accuracy of GPS PW depends on the zenith hydrostatic delay(ZHD) model and the parameter П.Through the error analysis on the ZHD calcu
