Shadow Technique for Improved Inversion of Lidar Data to Cirrus and ContrailOptical Depth (August 1992)

摘要

A striking feature of lidar images of back scattered signals from a cirrus cloud,received using an airborne upwardly measuring lidar system during the International Cirrus Experiment of 1989, is the shadowing by an underlying contrail. The lidar system can be calibrated with the aid of this shadowing, so that the extinction coefficients in the contrail are yielded with an accuracy of
