区域延迟模型在CORS站反演水汽中的应用
Application of Regional Delay Model in Inversion of Water Vapor in CORS Stations
摘要
Abstract
The basic principle and method of inversion atmospheric water vapor in the use of observation data from CORS system were systematically discussed, and the process of inversion atmospheric water vapor was analyzed. The Guangxi regional dry delay model and weighted average temperature model were established based on the sounding data. The tropospheric delay quantity along zenith direction was calculated with the observation data from Guangxi CORS station and domestic IGS station. After comparation of regional model and experience model, it was concluded that the regional model was available, the inversion of atmospheric water vapor and sounding water vapor were equal in precision. It showed the reliability of the model at last.关键词
