Abstract

A preliminary study of the synergism between active and passive spaceborne remote sensing systems has been conducted on the basis of new prospects for the implementation of lidar systems on space platforms for global scale measurements. Assuming a quasi-simultaneity in the measurements performed with an active backscatter lidar and with operational meteorological packages such as the Television Infrared Operational Satellite (TIROS)-N Operational Vertical Sounder radiometers, it is shown that combining both measurements could lead to an improvement in the accuracy of the retrieved vertical temperature profile in the lower troposphere. We used a modified version of the improved initialization inversion operational algorithm, to process the TIROS-N Operational Vertical Sounder data, taking into account the lidar measurements of cloud heights to define a temperature reference. New perspectives for the coupling of lidar and passive radiometers are discussed.
