Paper Abstract

When the ground-based GNSS station is observed, the accurate atmospheric Weighted Mean Temperature (Tm) cannot be obtained, which limits the application of GNSS in remote sensing water vapor. So this paper makes use of the Tm grid data provided by GGOS Atmosphere to interpolate at eight stations (Dalian, Qingdao, Shanghai, Xiamen, Shantou, Taizhou, Haikou and Xisha Islands) in coastal areas of China and evaluate the applicability of GPT2w in coastal areas of China. The results show that: 1) Tm obtained by interpolating four methods achieves the accuracy requirement of ground-based GNSS remote sensing water vapor; 2) the GPT2w model has good applicability in eightareas in the coastal areas of China.
