摘要
Abstract
The calculating methods of cloud cover and cloud surface radiative forcing based on the whole sky infrared image derived from WSICMS are analyzed in this paper. The scatter plots of the whole sky infrared radiation with the zenith angle are used to obtain the minimum radiation at each angle, by which the clear sky radiation and cloud cover can be calculated, and then the cloud cover and cloud surface radiative forcing are calculated and relationships between cloud surface radiative forcing and cloud cover are discussed. The results show that the cloud-flagged image are consistent well with the actual sky;there is a nonlinear relationship between the cloud surface radiative forcing at 8-14 μm and cloud cover, and similar results have derived from other data. It proves that the feasibility and accuracy of the study methods.关键词
