In this paper we present a comparison of temperature measurement data acquired with a lidar and a radiosonde at altitudes from 13 to 30 km. For the comparison we have selected a period (January-February), for which a maximal temperature variability exceeding 30 K is characteristic at altitudes of 25 km. Our lidar was about 210 km far from the meteorological station, but since the processes of air mass transport in the stratosphere are of a large scale (~1000 km), this comparison is well justified. The temperature profiles measured with the lidar and radiosondes proved to match very closely both qualitatively and quantitatively. The rms deviation between the profiles, calculated using 73 pairs of records, was 2.4 K. For a comparison, the estimate of the standard error of temperature reconstruction from lidar data was about ±5 K at an altitude of 25 km. The validation of the lidar measurements performed has confirmed their reliability.
