The work describes the results of theoretical and experimental studies of a possibility to use the meteorological lidar MEL-01 for remote measurements of main meteorological variables: temperature, humidity, and wind speed and direction. The experimental measurements of wind speed and direction profiles showed the lidar's efficiency in sounding the lower troposphere. Numerical modeling of measurements of atmospheric temperature and humidity profiles by the meteorological lidar MEL-01, using the method of differential absorption in the near infrared spectral region, showed that at middle latitudes in summer and in the tropics, a three-frequency method using the lines of absorption from the 0.72-<$E mu >m band is competitive with the two-frequency method of separate lidar temperature and humidity measurements. In winter conditions, especially at Arctic latitudes, a two-frequency method alone is practically realized.
