Description	Journal: Iop Conference Series: Earth and Environmental Science Atmospheric refraction error is one of the main factors affecting the accuracy of precision trigonometric levelling. The influence of it on height difference rises sharply with the increase of horizontal distance. In this paper, the elevation control survey data of Qinling mountains is used to calculate the atmospheric refraction coefficients among the areas in winter and summer, using the method of geometric levelling inverse calculation. Through the analysis of the change law of atmospheric refractive coefficient, the influence of atmospheric vertical refractive coefficient on trigonometric levelling in the Qinling Mountains is summarized, which provides a reference for trigonometric levelling in similar environments.
