Traditional aerosol lidar can not distinguish between changes in target reflectivity and attenuation between the lidar and the target


http://lidar.ssec.wisc.edu changes in target reflectivity and attenuation between the lidar and the target


Lidar Specifications changes in target reflectivity and attenuation between the lidar and the target
