Aerosol Classification by Advanced Backscatter Lidar Techniques
The high spectral resolution lidar (HSRL) method based on an iodine absorption filter and a frequency doubled pulsed Nd:YAG laser is presented. This method has the capability to directly measure the extinction and backscatter coefficients of aerosols and clouds. Measurements of an airborne HSRL system from four different field experiments are used to build up an aerosol classification. Two examples show the potential of this aerosol classification to distinguish between different aerosol types.
