Analysis uncovers how lidar properties depend on dust characteristics, suggesting impacts on classification models.

The research aims to understand how lidar scattering properties vary with the size and composition of absorbing dust aerosols.
Utilized TAMUdust2020 and triaxial-ellipsoid calculations for analysis.
Investigated parameters like lidar ratio, linear depolarization ratio, and single-scattering albedo.
Examined different limits of scattering theory: Rayleigh and geometrical-optics.
Lidar ratio shows a trend of S proportional to size parameter cubed in Rayleigh limit.
Linear depolarization ratio decreases in geometrical-optics limit as size parameter increases.
Single-scattering albedo remains small in Rayleigh limit and approaches a constant in geometrical-optics.

Luna et al. (2025) studied this question.
