Micro Pulse Lidar as a tool for active remote sensing of atmospheric particulate

摘要

Lidars have been employed in the investigation of instantaneous vertical structure of atmospheric particulate. Remote measurements of particle backscattering and aerosol extinction coefficient provide the altitude distribution of particles existence in the atmosphere. This paper describes the technology of micro pulse lidar employed for computation of altitude profiles of particle backscattering and extinction coefficient. The vertical distribution of particles in the atmosphere was derived using a code developed in MATLAB. Enhancement of particle vertical distribution during the period of 2007 Diwali was shown as a case study.
