Investigating the dependence of mineral dust depolarization on complex refractive index and size with a laboratory polarimeter at 180.0° lidar backscattering angle [PDF]
In this paper, the dependence of the particles' depolarization ratio (PDR) of mineral dust on the complex refractive index and size is for the first time investigated through a laboratory π-polarimeter operating at 180.0∘ backscattering angle and at (355,

Light scattering and absorption properties of dust particles retrieved from satellite measurements [PDF]
We use the radiative transfer model and chemistry transport model to improve our retrievals of dust optical properties from satellite measurements. The optical depth and absorbing optical depth of mineral dust can be obtained from our improved retrieval ...

Pollution affects Arabian and Saharan dust optical properties in the eastern Mediterranean [PDF]
Uncertainties in the direct radiative effect of mineral dust result from the variability in its optical properties but are also influenced by mixing with anthropogenic aerosols (“pollution”), e.g., black carbon or sulfates.

Understanding Haze: Modeling Size-Resolved Mineral Aerosol from Satellite Remote Sensing
Mineral dust aerosols are composed of a complex mixture of silicates, carbonates, oxides, and sulfates. The minerals’ chemical composition and size distribution are vital parameters to evaluate dust environmental impacts.
