Abstract

The lidar complex of the small station for high-altitude atmospheric sensing of the V.E. Zuev Institute of Atmospheric Optics SB RAS has been used in studies of the atmospheric thermal regime from 1994. The measurements are performed systematically and provide obtaining the vertical profiles of the air temperature for altitudes up to 70 km with a resolution of 192 m. It is of interest to compare the results with the data from other sources. The ERA5 reanalysis of the European Centre for Medium-Range Weather Forecasts (ECMWF), which summarizes the global meteorological monitoring network based on the retrospective data, provides high spatial (0.25×0.25°) and temporal (1 h) resolution. In the present report, the seasonal and annual distributions of vertical profiles of the statistical values of temperature deviation over Tomsk are considered according to the ERA5 reanalysis data relative to the lidar measurements. In addition, a similar comparison of lidar data was performed for the data of the AURA research satellite.
