Trigonometric leveling causes the precision damage because of the atmospheric refraction influence.This paper introduces the method to improve the recision with the measurement of air temperature,the pressure,intensity of pressure obtaining,the atmospheric refractive index and the atmospheric refraction offset angle.And it is proved that this method eliminates atmosphere refraction influence to the trigonometric leveling method.
