Dust‐associated sulfate is believed to be a key species which can alter the physical and chemical properties of dust particles in the atmosphere. Its occurrence in the particles has usually been considered to be the consequence of particles' aging in the air although it is present in some crustal minerals. Our observation at the north and south edge of Taklimakan desert, one of the largest dust sources in the Northern Hemisphere, during a dust episode in April 2008 revealed that sulfate in… 

Background-like nitrate in desert air

Limited production of sulfate and nitrate on front-associated dust storm particles moving from desert to distant populated areas in northwestern China

Abstract. Sulfate and nitrate compounds can greatly increase the hygroscopicity of mineral particles in the atmosphere and consequently alter the particles' physical and chemical properties. Their

Variability of dust mass concentrations and deposition rates under different weather conditions in Cele Oasis, southern Tarim Basin

Sand and dust invasions are a serious issue for oases; therefore, understanding the characteristics of dust concentrations, deposition rates, and influencing factors, under a variety of differing

Hygroscopic Properties of Saline Mineral Dust From Different Regions in China: Geographical Variations, Compositional Dependence, and Atmospheric Implications

Saline mineral dust particles, emitted from saline topsoil in arid and semiarid regions, contribute significantly to tropospheric aerosol particles. However, hygroscopic properties of saline mineral

First long-term detection of paleo-oceanic signature of dust aerosol at the southern marginal area of the Taklimakan Desert

The results collectively indicated that the dust aerosol from the Taklimakan Desert was characterized of evident paelo-oceanic signature as the Tak Limakan desert was found as an ocean in the ancient times from the perspective of paleogeology.

Elemental profiles and signatures of fugitive dusts from Chinese deserts.



Acidic processing of mineral dust iron by anthropogenic compounds over the north Pacific Ocean.

Atmospheric processing of mineral aerosol by anthropogenic pollutants may be an important process by which insoluble iron can be transformed into soluble forms and become available to oceanic biota.

Separated status of the natural dust plume and polluted air masses in an Asian dust storm event at coastal areas of China

[1] Asian dust particles usually refer to mineral particles which originate from arid and semiarid areas in the Asian continent and disperse eastward in a wide range in the atmosphere. Their

Mixing of Asian dust with pollution aerosol and the transformation of aerosol components during the dust storm over China in spring 2007

NO3 and NH4 decreased owing to the dilution of the local pollution by the invaded dust. The western dust contained relatively low anthropogenic aerosols, and it mainly derived from the Taklimakan

Morphological and chemical modification of mineral dust: Observational insight into the heterogeneous uptake of acidic gases

Aerosol samples were collected in the urban atmosphere of Beijing, China, by deploying a tethered balloon. Coarse particles (d > 1 μm) were individually analyzed using electron microscopes, to

Mineral aerosol particles collected in Dunhuang, China, and their comparison with chemically modified particles collected over Japan

[1] Continental China has been recognized as one of the most important sources of atmospheric mineral dust particles (called Kosa in Japan, which literally means yellow sand). Many investigators have

The influence on climate forcing of mineral aerosols from disturbed soils

AEROSOLS influence the global radiation budget1, and so changes in the atmospheric aerosol load due to either natural causes or human activity will contribute to climate change2. A large fraction of

Observation of nitrate coatings on atmospheric mineral dust particles

Abstract. Nitrate compounds have received much attention because of their ability to alter the hygroscopic properties and cloud condensation nuclei (CCN) activity of mineral dust particles in the
