The capabilities of orbital lidars to sense cloudiness are analyzed by the example of interpretation of the signals obtained with geodesic laser altimeters. A method is described of reconstructing the optical characteristics of cloudiness from the measured duration of signal returns at predetermined levels. The probabilities of occurrence of various magnitudes of attenuation coefficient and lidar ratio obtained by us are compared with the published data. Results of analysis of cloud returns of the altimeter confirm the capability of space-based lidars to yield reliable information and allow us to provide a basis for guiding their development.
