摘要： A single-line-extracted pure rotational Raman lidar system, including: a transmitter unit configured to emit extremely narrow-band laser light that is guided into atmosphere zenithward; a receiver unit configured to collect backscattered signals from the atmosphere; and a data acquisition and control unit configured to deliver data and guarantee automatic operation of the lidar system orderly. The transmitter unit employs a powerful injection-seeded Nd: YAG laser to emit 532.23 nm laser beam with a pulse energy of approximately 800 mJ, a repetition rate of 30 Hz and linewidth of
