[1]利用1996年10月30日至1997年6月30日在日本日同步先进地球观测卫星（ADEOS）平台上由法国国家空间研究中心（CNES）研制的地球反射偏振和定向宽视场成像光谱仪（POLDER）的观测资料，重新研究了海洋上气溶胶的特性。测量分析使我们假设气溶胶由具有双峰尺寸分布的颗粒组成，其中大颗粒模式通常由非球形颗粒组成。在所有观测中，从气溶胶散射的太阳辐射的光谱、方向和极化特征中有证据表明非球形颗粒的存在，Volten等人（2001）最近从实验室测量中得出的不规则颗粒的平均气溶胶散射矩阵证明提供了这些颗粒的非常有效的模型。
[1] The properties of the aerosols over the ocean are re-investigated by using the observations of the Polarization and Directionality of the Earth's Reflectance (POLDER) wide field of view imaging spectroradiometer developed by the Centre National d'Etudes Spatiales (CNES) and operated aboard the Japanese heliosynchronous Advanced Earth Observation Satellite (ADEOS) platform from 30 October 1996 to 30 June 1997. The measurement analysis leads us to assume that aerosols consist of particles with a bimodal size distributions, in which the large particle mode generally consists of nonspherical particles. In all observations where there is evidence for the occurrence of nonspherical particles from the spectral, directional, and polarization characteristics of the solar radiation scattered by the aerosols, the average aerosol scattering matrix for irregular particles derived recently by Volten et al. (2001) from laboratory measurements proves to provide a very efficient model of these particles.
