Abstract. In the present paper we describe an investigation of the accuracy of the intercomparison between the profiles of the atmospheric temperature measured by a rotational Raman lidar and radiosondes. The lidar measurement of the profile involves a reference point on the profile, where the temperature is measured by a contact thermometer. The dispersion of the difference between the values of the lidar and the radiosonde measurements is expressed by the dispersion of the measurement of the ratio of the lidar signals and the radiosonde temperature measurement, and the parameters of the lidar calibration. The experiment, carried out in the Planetary Boundary Layer at the edge of the city of Sofia, shows an agreement between the expected and the obtained accuracy although a deviation exists. This deviation is into acceptable limits and is explained by the inherited differences between the lidar and radiosondes as physical devices.
