Research Abstract

Quantitative estimates of global cloud microphysical properties are considered to be one of the essential elements toward a better understanding of the role of clouds in the climate system by improving their representation in climate models. The main outcome of this project is the refinement of global distribution of ice microphysical properties by the development of a reliable retrieval scheme for space-borne cloud profiling radar and lidar, which overcomes difficulties of applying earlier radar-lidar synergy algorithms to cloud grids where observation from only single instrument is available.
