Abstract:

The paper analyzes the structure parameter of the refractive index of optical waves C_n² in the surface air layer calculated from the structure parameter of the air temperature C_T². The C_n² estimates obtained from data of an optical differential turbulence meter and ultrasonic anemometer-thermometers are compared. The systematic difference between these estimates at the high degree of correlation is noted. The diurnal mean profile of C_n² in different seasons at territories with natural landscape and urban territory is obtained and analyzed.

Keywords:

refractive index, surface air layer, structure parameter, diurnal behavior, ultrasonic anemometer-thermometer
