Accurate temperature profiles with high spatiotemporal resolution play an essential role in atmospheric and space sciences. This paper reviews the main technical approaches to atmospheric temperature profiling using lidar, including pure rotational Raman lidar, Rayleigh lidar, high spectral resolution lidar, with particular emphasis on the development of the world's first single−line−extraction−based pure rotational Raman lidar by the group at Wuhan University, which has involved more than a decade of dedicated effort. This instrument enables precise extraction of individual spectral lines of N2 rotational Raman backscatter, and is capable of all−day accurate temperature profiling from near ground to the lower stratosphere (1~21 km during daytime and 1~35 km at night), with a measurement statistical error of 1 K below 21 km at night (and 11 km during daytime), without any external calibration. In addition, the measurements from this lidar allow direct retrieval of aerosol and cloud backscatter and extinction profiles with strict analytical expressions. Within the framework of Chinese Meridian Project observation network, this lidar is named "Temperature Profiling Lidar for Middle and Lower Troposphere". It has been deployed at Wuhan University, Wuchang station since 2022 and has recorded more than 420 days of high−precision atmospheric temperature profile observations.
