Abstract:MODIS data is taken as the research object, which can provide a global continuous atmospheric vapor distribution. We introduced the principle of the vapor inversion from MODIS data, and also studied the theory and method to establish regional tropospheric zenith wet delay model. We obtained the regional tropospheric zenith wet delay model of the Fenwei basin. It is verified that the model can reflect the terrainrelated wet delay, which provided a reference for the establishment of the regional tropospheric wet delay model in other regions, or doing it from other data.
