Determination of refraction anomalies by global inclinations of airstratas of identical density
Authors:Yu. A. Nefedjev  A. I. Nefedjeva
Abstract:This paper presents formulas for the calculation of the refraction anomalies caused by the inclination of atmospheric boundary layers. Anomalies were calculated for a few zenith distances for several different atmospheric models. It was established, that near Earth the atmospheric boundary layers have the global inclination in meridian plane near one minute of arc from North to South. They are calculated with standard deviation ±0.2′–±0.35′. The tilts are decreased gradually with the altitude and equal nearly 0 on the heights 8–10 km. Then direction of inclination is changed on opposite (from South to North) and maximum 1′ reaches on the heights 15–18 km. Next inclinations slowly decrease and equal 0 on the heights 28–30 km.
