Determination of mixing layer height using LIDAR

Abstract

Two lidar methods for determinatin of the MLH are compared. These methods are based respectively on the lidar signal gradient and the lidar signal variance. The two methods show excellent agreement, but with respect to the determination of MLH, variance method seems better. Both lidar methods are reliable in detecting the MLH, but the gradient method is showing comparatively lower altitudes, representing the center of the entrainment zone, where as the variance derived AML top shows the top of the aerosol mixing layer, determined by the mixing the upper edge of AML and free troposphere.
