Remote Sensing of Aerosol Extinction Using Single-Ended Lidars
Abstract
Aerosol extinction is one of the primary factors limiting the performance of systems which rely on visible or infrared radiation in the atmosphere. Lidars have been used to measure the backscattered radiation from aerosols in an attempt to determine extinction. However, techniques for inverting the power returned to a single-ended lidar to obtain range-dependent extinction coefficients requires a knowledge of the relationship between the backscatter and extinction coefficients along the path. If the aerosol distribution in the atmosphere is horizontally homogeneous, the need for knowing the relationship between backscatter and extinction can be eliminated by comparing the powers received from each altitude along two or more different elevation angles, and the extinction coefficient variation in the vertical direction can be determined.
