Transmissions at 0.75 and 1.65 μm can also be used to retrieve τ and re. 2. Study the impact of cloud inhomogeneity on the satellite retrieval simultaneously. Two 3D cloud fields, cumulus and stratocumulus fields are used in our study. The two cloud fields are generated with LES model and are adopted by the I3RC phase II. The BRDF at the wavelengths of 0.65 and 2.13 μm are calculated with SHDOM, and then the cloud optical thickness and effective particle radius are simultaneously retrieved using the MODIS algorithm.
