Atmospheric Optics and Radiation: History, Application, and Inspiration

This talk is intended mainly for young scientists, particularly, undergraduate and graduate students. Elastic electromagnetic scattering and the transfer of radiation are two important branches of applied physics, which are also fundamental to many other disciplines such as atmospheric remote sensing, bio-optics, and astrophysics. In this talk, I will review the history and evolution of these topics. Specifically, I will review the contributions by Clebsch, Lorenz, and Mie to the early development of the theory of light scattering by a sphere, and some recent developments in the numerical approaches (e.g., the DDA, FDTD and ray-tracing methods) for solving for the optical properties of nonspherical and inhomogeneous particles, as well as research efforts on the relevant applications to atmospheric remote sensing. In the review of the development of radiative transfer theory, we will focus on the early contributions by Lommel, Chwolson, Schuster, Eddington, Ambartsumian, Sobolev, and Chandrasekhar, just to mention a few. Especially, I will review Chandrasekhar's academic career and tremendous achievements. I hope that, after the talk, the students in the audience would be inspired by Chandrasekhar's legendary academic achievements and his dedication to science.
