ABSTRACT

This chapter presents an overview of various retrieval algorithms of cloud optical and microphysical properties developed for satellite passive spectral sensor measurements. These retrieval algorithms are based on different wavelengths (such as visible, infrared, CO2 absorbing bands, and so on) to utilize their advantages to derive accurate cloud properties. It also reviews some study cases employing the Moderate Resolution Imaging Spectroradiometer (MODIS), Advanced Geosynchronous Radiation Imager (AGRI), and Advanced Himawari Imager (AHI) radiometers to illustrate the current performance of satellite operational cloud products, and analyzes the factors contributing to the differences in cloud retrievals to present the development status of remote sensing of cloud properties. Although a number of mature algorithms for deriving cloud properties have been proposed and widely used for weather and climate studies, there are still some open questions that should be addressed in future research.
