Research Abstract

A next-generation-active-sensor-synergetic observation system that consists of Multiple-Field-of-View Multiple-Scattering Polarization Lidar, High spectral resolution lidar, and Doppler lidars was developed and successfully obtained key parameters for understanding the generation of clouds. This is the first time that the relation between vertical motions at cloud base and the kinetic fields of the atmosphere below cloud base was determined from observation. It was found that the formula obtained by Cloud Resolving Models significantly over-estimates vertical air-motion for cloud formation. We further proposed and applied the observation-based parameterization to unravel the global distribution of cloud-base vertical air-motion from space-borne cloud radar and lidar onboard CloudSat and CALIPSO satellites for improved representation of clouds in Earth System Models.
