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 ismathematically formulated in matrix solution formunder general anisotropic atmospheric conditions and convective boundary layer scenarios. Themethod 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 1064 nmwavelength case example is presented for a 40° elevation, two-angle azimuth scan, where horizontal wind speed and wind direction are retrieved.
