新疆地区GGOS Atmosphere加权平均温度的精化
Refinement of GGOS Atmosphere Weighted Mean Temperature in Xinjiang
摘要
Abstract
The application of ground-based GPS PWV inversion has been limited due to the inaccurately calculated the weighted mean temperature because most ground-based GPS fails to detect upper-air meteorological data.This paper analyzes the methods of obtaining the weighted mean temperature by deriving the data from GGOS atmosphere weighted mean temperature grid data in Xinjiang.By using the radiosonde data,this paper evaluates the accuracy of the weighted mean temperature (GTm) derived from GGOS atmosphere weighted mean temperature grid data considering seasonal and geographic variations.We then establish a refined model to correct (GTm).Results show that the (GTm)derived from mean value interpolation after correction using the refined model can meet the requirements of ground-based GPS precision PWV inversion in Xinjiang.关键词
