The backscattering optical properties of an ensemble randomly oriented dust particles at a wavelength 355 nm were comprehensively studied by examining the invariant imbedding T-matrix results super-spheroid model. In particular, we focused on lidar ratio ( S ) and depolarization δ relations aerosols to aid interpretation data from Atmospheric Lidar (ATLID) instrument that will be onboard Earth Cloud, Aerosol Radiation Explorer (EarthCARE) satellite. Super-spheroid models with various aspect...
We report a new implementation of the invariant imbedding T-matrix (IITM) method based on discrete spherical grid approach for representing particle shape and internal inhomogeneity. The version IITM (referred to as IITM-discrete) improves flexibility IITM-especially inhomogeneous particles. It is much more convenient specifying morphology in electromagnetic wave scattering simulations. Particle represented by series layers ranging from inscribed sphere circumscribed sphere. Spherical are...
Abstract. Mineral dust particles are typically nonspherical and inhomogeneous; however, they often simplified as homogeneous spherical for retrieving the refractive indices from laboratory measurements of scattering absorption coefficients. This study theoretically investigated uncertainties in corresponding optical properties resulting this simplification at various sizes within wavelength range 355 to 1064 nm. Different numerical experiments were conducted under both ideal realistic...
Abstract. Mineral dust particles are nonspherical and inhomogeneous; however, they often simplified as homogeneous spherical for retrieving the refractive indices from laboratory measurements of scattering absorption coefficients. The retrieved then employed computing optical properties or model with downstream applications. This study aims to theoretically investigate uncertainties involved in aforementioned rationale based on numerical simulations focuses a wavelength range 355–1064 nm....
