Paper Abstract

It is of great interest to investigate the radiative properties on the cloud optical, microphysical, and geometrical properties of clouds that play crucial role in the climate system. Here, top height, base height, and geometrical thickness of cloud layer are considered as cloud geometrical properties. Several studies show that information of some spectral regions including oxygen A-band, enables us to retrieve the cloud geometrical properties as well as the optical thickness, the effective particle radius of cloud. In this study, an algorithm was developed to retrieve simultaneously the cloud optical thickness, effective particle radius, top height, and geometrical thickness of cloud layer with the spectral information of visible, near infrared, thermal infrared, and oxygen A-band channels. This algorithm was applied to ADEOS-II / GLI dataset so as to retrieve global distribution of cloud geometrical properties. The retrieved results around Japan are not strange and to be validated with other observation in the near future. This study will expand to the global analysis and be anticipated to contribute to the earth climate studies in terms of cloud optical, microphysical, and geometrical properties.
