我们提出了一个方案的细节反演卷云光学厚度和有效粒子大小从最低点观察反射率测量。使用两个近红外波长，一个具有可忽略的冰吸收（1.04 μm），另一个具有显著的冰吸收（1.55 μm）。该方案中使用了四种冰晶形状：冰球、六方柱、六方板和随机多晶体。我们强调的敏感性检索的相函数的形状，这是从特定的冰晶形状假设。
We present details of a scheme for retrieving cirrus cloud optical thickness and effective particle size from nadir‐viewing reflectance measurements. Two near‐infrared wavelengths are used, one with negligible ice absorption (1.04 μm) and one with significant ice absorption (1.55 μm). Four ice crystal shapes are used in the scheme: ice spheres, hexagonal columns, hexagonal plates and randomized polycrystals. We highlight the sensitivity of the retrievals to the shape of the phase function, which follows from the particular ice crystal shape assumed.
