| 520 | 3 | |a The methodological issues of lidar measurements of the vertical distribution of atmospheric temperature up to altitudes of 90 km are considered. The method is based on lidar measurements of the vertical profile of atmospheric molecular density using the Rayleigh scattering effect. The results obtained in the upgraded channel of the Rayleigh scattering of the 2.2-m diameter lidar based on the main mirror of the Siberian Lidar Station (SLS) are discussed. One of problems in carrying out measurements with the use of large-diameter telescopes is the giant dynamic range of lidar responses. The work with this range requires special attention both to the methodology and to the experimental technique. For solving this problem, an improved technique for the retrieval of temperature from molecular backscattering lidar signals is proposed. Numerical experiments have shown that the accuracy of the temperature profile retrieval depends on the choice of the position of the calibration point and the error in setting the temperature in it. The technique of the temperature profile retrieval, when the calibration point is chosen at the top of a sounding path, is sufficiently stable even under conditions of a giant dynamic range of lidar responses at the SLS. The comparison of the results of temperature retrieval from the real lidar responses with the satellite measurement data revealed significant discrepancies associated with the distorting instrumental and atmospheric effects on the lidar signal shape. A correction procedure based on the lidar calibration can significantly reduce measurement errors. | |
