Polarization of Infrared Waves Caused by Propagation through the Atmosphere
Abstract
The study presents an investigation of the polarization of infra-red waves due to propagation through the atmosphere. Cumulus cloud and Haze M particle size distributions are considered for various optical depths at wavelengths of 4.0 and 10.0 micrometers. Results at these wavelengths are compared to results at a wavelength of 0.5 micrometers for the same physical atmosphere. Initially the radiative transfer integral equations are derived which include the Stokes polarization vector. From these integral equations a Monte Carlo simulation technique is used to photon histories through the atmosphere. The effects of multiple scattering on the polarization state of the scattered intensity is included. A diffuse scattering ground which causes complete depolarization of the incident intensity is included in the simulation model.
