Observation of the stratospheric temperature above Nanjing with Rayleigh lidar

Long-term observation of stratospheric temperature was conducted using Rayleigh lidar, in order to understand variation regularities of the stratospheric temperature. The analysis results of the observation dataset show that, the tratospheric temperature was affected by gravity wave, the breakdown of gravity wave led to temperature increasing, and the scope of variation was about 12%; temperature increased in lower stratosphere and decreased in upper stratosphere during April and October; in the aspect of inter-monthly variation, stratospheric temperature was relatively stable except the influence of the planetary wave, and there were differences between Rayleigh result and the model. Furthermore, the information of gravity wave was retrieved from the temperature profile.
