AbstractCloud top height could be retrieved by polarized information. In order to reduce the uncertainty of retrieval results caused by the variability of cloud and surface polarized properties, the multi-angle polarized information of 490 nm band and 865 nm band was used to retrieve cirrus cloud top height. Atmospheric top polarized information and the differences of atmospheric top polarized information between 490 nm band and 865nm band was theoretically analyzed, which showed that it was feasible to retrieve cirrus cloud top height using polarized reflectance difference between 490 nm band and 865 nm band. Cirrus cloud was assumed as General Habit Mixture (GHM) model, the polarized reflectance difference was evaluated by the vector radiative transfer model based on adding-doubling method, and the sensitivity of polarized reflectance to cirrus cloud effective radius, optical thickness and cloud top pressure were evaluated. The results show that when the cirrus cloud optical thickness is greater than 3, the polarized reflectance difference is not sensitive to the change of effective particle radius and optical thickness, and is sensitive to the change of cloud top pressure. The polarized reflectance difference look-up table was constructed by choosing appropriate parameters according to sensitivity analysis, and retrieved cirrus cloud top heights using look-up table method base on POLDER3 data. The retrieval results were compared with POLDER3 product and MODIS product. The results indicate that compared with the official POLDER3 algorithm, the polarized reflectance difference look-up table method could applied to a wider scattering angle range, and had a better consistency with MODIS product.
