Abstract

A multi-wavelength aerosol lidar (MWAL) with 355 nm, 532 nm and 1064 nm has been developed and deployed for operational observations at Haidian District Meteorological Service of Beijing. The structure design, specifications, observation campaign and detection principle of the MWAL are presented and the retrieval method of boundary layer height is introduced. By comparing it with the data of digital radiosonde, it is verified that the first normalized gradient of range corrected signal can more accurately retrieve boundary layer height. The typical daily variation characteristics and influencing factors of urban boundary layer height are analysed through observation examples, and the monthly mean value of boundary layer height in 2019 is acquired and analysed.
