The method of determination of refraction parameters based on analysis of slopes of the atmospheric layers

In this article we propose a method for determination of refraction parameters taking into account the slopes of the adjacent atmospheric layers. The refraction parameters at several zenith distances and for different models of the atmosphere were calculated for illustration. As a result it was obtained that near the Earth the layers of the atmosphere have slopes in the meridian plane from north to south within one arcminute with an accuracy of $\pm0.18\div\pm0.32$ arcminute. The slopes decrease uniformly proportional to the height and are $0^\circ$ at 9 km. The slopes of the layers change to the reverse ones and reach a maximum of 1 arcminute at heights of 20 km. Then the slopes decrease gradually and go to $0^\circ$ at heights of 30 km.
