Abstract. Refraction of radio waves in the VHF band in the lower neutral part of the atmosphere (troposphere) can be calculated from the values of the altitude profile of the refractive index of air (n). The refractive index mainly depends on the atmospheric pressure, temperature and humidity of the air. In order to obtain data on temperature and relative humidity at different atmospheric pressure levels, in addition to the radiosonde method, the possibility of using passive satellite location of the atmosphere is considered for modeling the altitude dependence of the refractive index of air. The seasonal parameters of the exponential model of tropospheric refraction and the values of the angles of total refraction for different heights of the radiation source above the Earth's surface are determined above the observation points of Tiksi, Norilsk and Vize Island. The values of total tropospheric delay obtained as a result of GPS measurements are considered.

Key words: refractive index, vertical profiles, refraction angle, GPS measurements, tropospheric delay.
