Abstract: his study analyzed the global and seasonal characteristics of cloud phase and ice crystal orientation (CTYPE-lidar) by using the Cloud?Aerosol Lidar with Orthogonal Polarization (CALIOP) on board the Cloud?Aerosol Lidar ...

Evaluations of the Thermodynamic Phases of Clouds in a Cloud-System-Resolving Model Using CALIPSO and a Satellite Simulator over the Southern Ocean

Source: Journal of the Atmospheric Sciences:;2020:;volume( 77 ):;issue: 011:;page 3781

Author(s): Roh, Woosub;Satoh, Masaki;Hashino, Tempei;Okamoto, Hajime;Seiki, Tatsuya

Publisher: American Meteorological Society

Abstract: A new evaluation method for the thermodynamic phases of clouds in cloud-system-resolving models is presented using CALIPSO observations and a satellite simulator. This method determines the thermodynamic phases using the ...

Melting Layer Cloud Observed during R/V Mirai Cruise MR01-K05

Source: Journal of the Atmospheric Sciences:;2006:;Volume( 063 ):;issue: 011:;page 3020

Author(s): Yasunaga, Kazuaki; Yoneyama, Kunio; Kubota, Hisayuki; Okamoto, Hajime; Shimizu, Atsushi; Kumagai, Hiroshi; Katsumata, Masaki; Sugimoto, Nobuo; Matsui, Ichiro

Publisher: American Meteorological Society

Abstract: In this study, cloud profiling radar and lidar were used to determine the frequency distribution of the base heights of cloudy layers with little (or no) falling condensate particles. The data were obtained from stationary ...
