Middle Atmospheric Density and Temperature Detection Using Rayleigh Lidar

The vertical distribution of middle atmospheric density and temperature can be obtained in the altitude range 30 to 90 kilometer by using Rayleigh Lidar. According to the data from actual measurement, the inversion results are in good agreement with those of the standard atmosphere model CIRA86. Generally, in the altitude range 30-65 km, the deviation of the atmospheric density measured by the Lidar from that of CIRA86 is no more than 5%, and the deviation of the temperature is less than 3 k. However, the deviation of the temperature above 75 km is very large.
