This paper analyses several common methods of atmospheric refraction correction, and puts forward a new method: without meteorological parameter observation, utilizing the vertical angles and distances of double-prism in tsigonometric leveling, it works out atmospheric refraction coefficient by atmospheric refraction angle deviation directly.
