The atmospheric temperature profile and its time-dependent variation have many applications in geophysical research area, thus a Rayleigh-Raman temperature lidar was constructed to obtain atmospheric temperature profiles with high spatial and temporal resolution. This paper, introduces the temperature measurement principle and the key parameters of the Rayleigh-Raman lidar. In terms of the temperature inversion algorithms, background noise subtraction and the wavelet denoising algorithm are used to enhance the signal to noise ratio. Comparisons between the measurement of our lidar and atmospheric data model, satellite measurements are conducted, respectively. The results show good agreements and verify the accuracy of the lidar system, which means the lidar measurement can be used in the meteorological research areas.
