论文摘要
在这封信中，我们利用光的极化特性来研究描述两个波长之间光学反向散射的波长依赖性的逆势指数。如果先前对Angstroem指数的解释是颗粒尺寸指示剂的解释，则光线极化的使用可以通过分别检索在大气颗粒混合物中包含的粒子和非球形粒子的反向散射驱动的驱动器指数，从而研究了对粒子形状的依赖。作为输出，麦克斯韦方程的分析解，可以应用洛伦兹MIE理论，小球模型，以研究每个分配形状的颗粒大小和复杂的折射率的依赖性。有趣的是，LiDAR检索了特定于S和NS颗粒的反向散射驱动器指数的垂直曲线，可以用来评估两种颗粒形状的粒子大小和复杂的屈光度指数，用于两个颗粒形状，无球体和非球形，我们在案例研究中远程研究，因为我们在一个专门用于粉尘的粉尘事件上都在案例研究中表现出来。
In this letter, we exploit the polarization property of light to investigate the Angstroem exponent describing the wavelength dependence of optical backscatter between two wavelengths. Where previous interpretation of Angstroem exponent was that of a particles size indicator, the use of light polarization makes it possible to investigate the Angstroem exponent dependence on the particles shape by separately retrieving the backscattering Angstroem exponent of the spherical and nonspherical particles contained in an atmospheric particle mixture. As an output, analytical solutions of the Maxwell equations, Lorenz Mie theory, spheroidal model,can then be applied to investigate the Angstroem exponent dependence on the particles size and complex refractive index for each assigned shape. Interestingly, lidar retrieved vertical profiles of backscattering Angstroem exponents specific to s and ns particles can be used by the optical community to evaluate a range of involved particles sizes and complex refractive indices for both particles shapes, spherical and nonspherical, as we remotely demonstrate on a case study dedicated to a dust nucleation event.
