Light scattering and absorption properties of dust particles retrieved from satellite measurements [PDF]

, 2008
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 ...

Aerosol Mineralogical Study Using Laboratory and IASI Measurements: Application to East Asian Deserts

Remote Sensing, 2022
East Asia is the second-largest mineral dust source in the world, after the Sahara. When dispersed in the atmosphere, mineral dust can alter the Earth’s radiation budget by changing the atmosphere’s absorption and scattering properties.

Long-term (2002–2012) investigation of Saharan dust transport events at Mt. Cimone GAW global station, Italy (2165 m a.s.l.)

Elementa: Science of the Anthropocene, 2016
Mineral dust transport from North Africa towards the Mediterranean basin and Europe was monitored over an 11-y period (2002–2012) using the continuous observations made at Mt. Cimone WMO/GAW global station (CMN).

Pollution affects Arabian and Saharan dust optical properties in the eastern Mediterranean [PDF]

Atmospheric Chemistry and Physics
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.

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study [PDF]

, 2015
The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the ...

Carbon sequestration in the deep Atlantic enhanced by Saharan dust [PDF]

, 2017
Enhanced atmospheric input of dust-borne nutrients and minerals to the remote surface ocean can potentially increase carbon uptake and sequestration at depth.

Understanding Haze: Modeling Size-Resolved Mineral Aerosol from Satellite Remote Sensing

Remote Sensing, 2022
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.

Saharan dust deposition may affect phytoplankton growth in the mediterranean sea at ecological time scales [PDF]

, 2014
The surface waters of the Mediterranean Sea are extremely poor in the nutrients necessary for plankton growth. At the same time, the Mediterranean Sea borders with the largest and most active desert areas in the world and the atmosphere over the basin is

3+2 + X: what is the most useful depolarization input for retrieving microphysical properties of non-spherical particles from lidar measurements using the spheroid model of Dubovik et al. (2006)? [PDF]

, 2019
The typical multiwavelength aerosol lidar data set for inversion of optical to microphysical parameters is composed of three backscatter coefficients (β) at 355, 532, and 1064 nm and two extinction coefficients (α) at 355 and 532 nm.
