Corrections for Atmospheric Refraction in Precise Leveling
The error of atmospheric refraction is one of the main systematic errors in precise leveling. Through many years of tests and studies, the author has selected a model of temperature more applicable to practice and derived a strict formula for calculating the atmospheric refraction in leveling. Satisfactory result has been obtained in the test levelings, thus the foundation has been laid for the practical application in the future.
