摘要
加权平均温度(Tm)在地基GPS反演大气水汽中尤为重要,对广西地区大气加权平均温度的时空变化特性进行了分析,创建了广西地区的Tm模型,对不同模型加权平均温度进行对比,结果表明:广西模型的精度良好,结算结果有所提高。
The weighted average temperature(Tm)is particularly important in the ground-based GPS retrieval of atmospheric water vapor.Analyzed the spatiotemporal variation characteristics of the atmospheric weighted average temperature in Guangxi and creates the Tm model in Guangxi.The comparison of weighted average temperatures of different models showed that the accuracy of Guangxi model was good and the settlement results were improved.
