Determination of aerosol extinction-to-backscatter ratios from simultaneous ground-based and spaceborne lidar measurements.

A technique that determines the aerosol extinction-to-backscatter ratio (lidar ratio) as well as extinction and backscatter coefficients from simultaneous downlooking and uplooking lidar measurements is described. The feasibility of this technique is demonstrated by applying the technique to data acquired by the cloud-aerosol lidar pathfinder satellite observation (CALIPSO) lidar measurements and ground-based lidar measurements made at Hampton University (37.02 degrees N, 76.34 degrees W).
