Contrasting mineral dust abundances from X-ray diffraction and reflectance spectroscopy [PDF]

Atmospheric Measurement Techniques, 2022
Mineral dust particles dominate aerosol mass in the atmosphere and directly modify Earth's radiative balance through absorption and scattering. This radiative forcing varies strongly with mineral composition, yet there is still limited knowledge on the ...

Numerical simulation on flow and evaporation characteristics of desulfurization wastewater in a bypass flue

Engineering Applications of Computational Fluid Mechanics, 2020
Owing to the oversimplification of the evaporation model, existing numerical analysis cannot accurately characterize the evaporation characteristics, which has limited its significance for engineering.

Heterogeneous reactions of mineral dust aerosol: implications for tropospheric oxidation capacity [PDF]

Atmospheric Chemistry and Physics, 2017
Heterogeneous reactions of mineral dust aerosol with trace gases in the atmosphere could directly and indirectly affect tropospheric oxidation capacity, in addition to aerosol composition and physicochemical properties.

A new optical-based technique for real-time measurements of mineral dust concentration in PM₁₀ using a virtual impactor [PDF]

Atmospheric Measurement Techniques, 2020
Atmospheric mineral dust influences Earth's radiative budget, cloud formation, and lifetime; has adverse health effects; and affects air quality through the increase of regulatory PM10 concentrations, making its real-time quantification in the atmosphere

Nitric acid scavenging by mineral and biomass burning aerosols [PDF]

, 1998
The abundance of gas phase nitric acid in the upper troposphere is overestimated by global chemistry-transport models, especially during the spring and summer seasons.

Modelling mineral dust emissions [PDF]

IOP Conference Series: Earth and Environmental Science, 2009
The biogeochemical cycle of mineral dust is of major interest to understand climatic changes. Moreover, these particles can also cause risks for human health and societal activities in regions in the neighbourhoods of arid and semi-arid source areas of dust emission.

Using aircraft measurements to determine the refractive index of Saharan dust during the DODO Experiments [PDF]

, 2010
Much uncertainty in the value of the imaginary part of the refractive index of mineral dust contributes to uncertainty in the radiative effect of mineral dust in the atmosphere.

The implementation of dust mineralogy in COSMO5.05-MUSCAT [PDF]

Geoscientific Model Development
Mineral dust aerosols are composed of a complex assemblage of various minerals depending on the region in which they originated. Given the different mineral composition of desert dust aerosols, different physicochemical properties and therefore varying ...

Characteristics of Chemical Solutes and Mineral Dust in Ice of the Ablation Area of a Glacier in Tien Shan Mountains, Central Asia

Frontiers in Earth Science, 2022
Diverse microbial communities live on glacial surfaces, with abundances and diversities dictated by the chemical and physical conditions of the supraglacial environment. Chemical solutes and mineral dust on glacial surfaces are generally derived from the
