Abstract

The retrieval of radiative properties of cold clouds at the global scale is an important challenge for the understanding of climate change. Amongst other objectives, the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) mission, developed in collaboration between NASA and CNES - planned to be launched in 2004 -, aims at improving our knowledge of semi-transparent cold clouds. Cloud emissivity and particle size will be retrieved using combined measurements from an infrared imaging radiometer (IIR) developed in France and a backscatter lidar developed in the USA. The concept of the instrument and the algorithm principle are presented. Synergism between lidar and IR radiometer instruments is discussed in the frame of the algorithm development.
