| Abstract: | The basic theory and mathematical model of ground-based GPS meteorology are introduced namely how to precisely isolate the wet component of tropospheric delay and then to reliably convert it into Precipitation Water Vapor(PWV).From the measured GPS data of five International GNSS Service(IGS) sites locating in the China region the PWV are inversed by using Bernese 4.2 software,the relation between the PWV and the rainfall is subsequently analyzed and the feasibility of GPS-based weather forecast is finally explored. |
