新疆地区地基GPS加权平均温度模型的建立与分析
Model establishment and analysis of weighted mean temperature of ground-based GPS in the region of Xinjiang
摘要
Abstract
The correlation analysis of Tm and Ts was made by 5 gears data from Xinjiang Sounding station.On this basis,the Tm model of single station and region of Xinjiang are established by linear regression.It concludes that the correlation of Tm-Ts and the coefficient of regression formula vary based on the transportation of geographic position in a certain regularity.The relationship between the strength of the correlation and the precision of the Tm-Ts regression model is not proportional.In Xinjiang,the accuracy of single station model is better than some several important models in recent years documents.As the practical scope of a single station model is limited,it is necessary to establish a regional model.The linear regression regional model is Tm =103.338 8 + 0.592 3 Ts,the accuracy of regional model is higher than previous models in the internal and external precision.关键词
