Abstract

Clouds play a crucial role in the climate system. The investigation of their radiative properties on the cloud optical, microphysical, and geometrical characteristics is of great interest. 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 and 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. For the preparation of global analysis, we look into the look up tables for the sensitivity of cloud optical thickness, particle size, top height, and geometrical thickness. This study will expand to the global analysis and is anticipated to contribute to the earth climate studies in terms of cloud optical, microphysical, and geometrical properties.
