摘　　要：利用天津地区9个GPS连续观测站两年的数据,及4个IGS参考站的观测数据,计算分析了天津地区GPS连续观测站天顶对流层延迟的年周期变化,以及不同位置的GPS站天顶对流层延迟的时空相关性。其中站间互差的均值为±4 mm左右,标准差优于1 cm;2006年和2007年互差的均值约为9 mm,标准差优于4 cm。The annual period changes of zenith tropospheric delay for two years were calculated from the observations of 9 GPS continuously operating stations in Tianjin area as well as 4 IGS reference staions, and the timespace correlations of zenith tropospheric delay at different locations were analyzed. The results show that the mean values of differences among stations are about ± 4 mm , the standard errors are better than 1 cm ; the mean values of differences between the data of 2006 and 2007 are about 9mm , the standard errors are better than 4cm.
