Wind retrieval from multiangle backscatter lidar profiles through anisotropic aerosol structures

Abstract

A wind retrieval correlation method for backscatter lidar scanning schemes consisting of a few profiling sounding lines of sight is mathematically formulated in matrix solution form under general anisotropic atmospheric conditions and convective boundary layer scenarios. The method assumes the frozen atmosphere model and works with temporal cross-correlation functions that do not need to be maximized. The method also applies to the well-known case of slant scans based on the multiple-angle azimuth technique (horizontal wind retrievals). A first application of the method to a 1064nm wavelength case example is presented for a 40 degrees elevation, two-angle azimuth scan, where horizontal wind speed and wind direction are retrieved.
