Abstract:
The practical use of the refraction coefficient k (integral of the temperature gradient) is limited with spatial-temporal changes of the atmosphere’s meteorological parameters quantitative characteristics. These restrictions are eliminated on applying similarity theory to the problem of taking into account the refraction in leveling. Multi-year attempts of the corrections ‘ determination are based on using the gradients of temperature, or related quantities, obtained by weather-logical measurements that are one or two (more) orders of magnitude inferior to the accuracy of the gradient – based geodetic observations. The solution of the problem is to determine the gradient simultaneously with the geodetic measurement of altitudes through the use of readily available quantities for direct measurement. They are: the temperature gradient γ1 at a height z equal to 1 m, and the average height of the sighting beam zср above the earth’s surface.
