Abstract : The results of helicopter sounding of the atmosphere at 0400, 0700, 1000, 1200 and 1530 hours Moscow time were used for determining the variability of the coefficient of refraction. At 0400 hours the refractive index of dry and moist air decreases with altitude. At 0700 hours dry decreases below the 500-m level and moist increases insignificantly above that level. At 1000, 1200 and 1530 hours moist has its maximum value at the earth's surface and decreases slowly with height. The mean values of temperature, pressure and humidity were used in computing N. The results of computations show that the differences in the mean values N, computed by different methods, do not exceed 1.3 unit. (Author)
