Abstract: A set of rules is implemented to horizontally scanning aerosol lidar snap shots to robotically and objectively decide wavelength and orientation of atmospheric cover waves. The Outcomes are as compared with formerly published subjective estimates. The information used are from the 2007 Canopy Horizontal Array Turbulence Study. Fifty three episodes of cover waves with wavelengths starting from 30 to a hundred meters were recorded over three months. This presentation describes the set of rules and the outcomes. The set of rules begins through calculating an autocorrelation function (ACF) for a square subset of pixels that contain cover waves from a unmarried lidar experiment picture in a Cartesian coordinate system. The set of rules then calculates the common of the ACF in a sequence of concentric earrings across the beginning. The radius of the second one maximum common corresponds to the wavelength. Next, the common of the ACF is calculated over a slim variety of angles with admire to north from the beginning and extending outward to the radius that corresponds to the wavelength acquired withinside the preceding step. This step is repeated for consecutive bands of angles in a clockwise fashion Outward to the radius that corresponds to the wavelength acquired with inside the preceding step.
