Lidar volumetric signals through random surface of ocean

In applying an ocean lidar equation, a reflectance and a refractivity of a random surface of the water is the most difficult parameter for an actual ocean lidar observation. A flight test of an airborne ocean lidar and a surface test of a shipboard ocean lidar showed variations of intensity of light scattered from a depth of the water. We built a multiparameteric shipboard ocean lidar to examine a hypothesis that variations of light scattered or fluorescence from the depth could be given as a function of light reflected at the surface of the water. As a result, we have confirmed that light scattered or fluorescence from the depth was independently given from variations of light reflected at the surface of the water on the current lidar system.
