Paper Abstract

Cirrus is important in the energy balance of the earth-atmosphere system. Previous studies are based on the forward models using the single scattering in the cirrus. In this study, we provide a unique method to detect the cirrus using the polarized reflectivities, single-scattering, and optical properties of water and ice with Moderate Resolution Imaging Spectrometer (MODIS) observations. Consequently, the polarized reflectivities at MODIS 1.375 μm channel show the reasonable characteristics of the cirrus. The effective refractive indexes are retrieved approximately from 1.1 to 1.4. This investigation provides an effective inversion procedure for detecting the cirrus using the physical characteristics in the cirrus on the basis of the polarization and refractive index.
