Measurements of vertical profile of wind speed and direction at the Resource Center "Observatory of ecological safety" of Research Park of St. Petersburg State University in the city center for several months of 2014–2015 are presented. The observations were accomplished using the Doppler lidar. The height of laser wind sounding was limited by lidar characteristics and atmospheric conditions to an average of 1.5–2 km, with the maximum of 6 km. The results were compared with the data of aerial radio sounding performed at Voeikovo aerological station. The distance between the observational points was 25 km. The comparison was made with the assumption of wind field homogeneity on such a scale. In most cases, there is a good agreement between the observed vertical profiles of wind obtained by both methods. The cases where the results differ sharply either at high altitudes or, on the contrary, at the surface layer were, however, identified and explained.
Keywords: Doppler lidar, wind velocity, wind direction, radiosonde, vertical profile, meteorological parameters
