Abstract: nlike other cloud types, high-level clouds play an important role, often imposing a warming effect, in the earth?atmosphere radiative energy budget. In this paper, macro- and microphysical characteristics of cirrus clouds, ...

Abstract: The threshold method is commonly used to determine cloud in a sky image. This paper evaluates the method by numerical simulation and shows that the aerosol optical depth (AOD) is a key factor that influences the accuracy. ...

Abstract: aked-eye observation of cloud cover has widely resisted automation. Replacement of human observation by instruments is an inexorable trend for the development of ground-based macroscopic cloud observation. In this paper, ...
