Considering the fact that refraction effect of radio wave in atmosphere becomes a main error source of data quality from ground stations. Using the previous ground data and actual meteorological sounding data of Xiamen region, it builds a vertical distribution model of atmospheric parameters and calculates height vertical distribution data of atmospheric refraction in this region. Then it analyzes the characteristics of changes of meteorological factors in troposphere over this region and their effect on the refractive index. To be specific, it compares the forecast accuracy of three models including ITR-U Model, segmented model, and Hopfield Model with the measured atmospheric refractive index data in this region. The forecast accuracy of different refractive index models applied in the same region is comparatively analyzed. Finally, the effect of the models is measured by using the root-mean-square error so as to denote the useable ranges of three models, which shed a certain light on studying measure-control precision of TT&C systems in China.
