Development and applications of a micropulse lidar

Abstract

Abstract:

A micropulse lidar (MPL) system is being developed by Shandong Academy of Sciences Institute of Oceanographic Instrumentation (SDIOI) to study and investigate structural and optical properties of clouds and aerosols. It is being built using commercially available, off the shelf, components. The transmitter is based on a diode-pumped Nd:YAG laser which delivers up to 6 μJ pulse energy at a pulse repetition rate of 2.5 kHz. The receiver utilizes a commercial 20-cm diameter Schmidt-Cassegrain telescope, a 0.5 nm narrowband interference filter, and a photon counting PMT detector. The tropospheric atmospheric aerosol of Qingdao was observed with the system and results show that it can measure the tropospheric aerosol continuously and well reflect the space and time distribution of aerosol.

Key words: micropulse lidar, aerosol, extinction coefficient
