Research Abstract

We developed the cloud detection method using CloudSat and CALIPSO data. Our cloud mask results for CALIPSO have less contamination by noise and aerosols compared with the standard CALIPSO mask, Vertical Feature Mask. Then we developed cloud particle type discrimination method for CALIPSO. Finally we developed a new radar-lidar algorithm that can be applied to CloudSat and CALIPSO data in order to retrieve ice cloud miacriphysics.
