High Potential of Asian Dust to Act as Ice Nucleating Particles in Mixed‐Phase Clouds Simulated With a Global Aerosol‐Climate Model

Journal of Geophysical Research: Atmospheres, 2021
Mineral dust affects the microphysical and radiative properties of mixed‐phase clouds and hence the radiative balance of the Earth by acting as ice nucleating particles (INPs). However, the importance of Asian dust as INPs is not well understood. In this

Asian dust impacts on heterogeneous ice formation at Wuhan based on polarization lidar measurements

, 2021
We analyzed 456 thin mid-level cloud layers based on two-year polarization lidar measurements in Wuhan (30.53°N, 114.37°E), China. Dust separation algorithm based on lidar measurements was implemented to identify clouds under influences of dust and non ...

On eastern Asian dust storm

Advances in Atmospheric Sciences, 1990
In this paper, the characteristics of eastern Asian dust storm are examined with emphasis on the satellite measurements of aerosol optical thickness. The reflectivity of solar radiation from the earth's atmosphere depends on the optical thickness. The satellite measurement of radiance of sunlight, scattered by the earth and its atmosphere, is used to ...

Asian dust events: Environmental significance in Beijing

Journal de Physique IV (Proceedings), 2006
The environmental significance of dust storms (impact on air quality, climatic effects, health effects) is described first in a general terms then in context with the local environment of metropolitan Beijing, China. The regional characteristics of dust storms in China, their sources and transport pathways, the chemical composition and the mixing and ...

Characterization of Asian dust storm and non-Asian dust storm PM2.5 aerosol in southern Taiwan

Atmospheric Environment, 2006
Abstract High winds that blow sand from the desert regions of central Asia to points east are commonly known as Asian dust storms (ADS). In this paper we study the impact of an ADS on the PM2.5 aerosol extant in Tainan, a city in southern Taiwan. PM2.5 aerosol was collected at an urban and a coastal site in Tainan before the ADS (4–12 January 2001 ...

Effect of Asian dust on respiratory symptoms among children with and without asthma, and their sensitivity.

Science of the Total Environment, 2020
There has been little study on the effect of Asian dust exposure on respiratory symptoms among children who are vulnerable to environmental factors. In this panel study, we investigated the effect of Asian dust on respiratory symptoms among children with

Central Asian Dust Experiment (CADEX) and Comparison of Lidar Ratios of Asian and Saharan Dust

Light, Energy and the Environment, 2016
We report about first aerosol lidar measurements that were performed in Dushanbe, Tajikistan (Central Asia) during our Central Asian Dust EXperiment (CADEX) project. The determined intensive property depolarization ratio allows an aerosol characterization and often shows mineral dust at lofted layers during spring time and optically and geometrically ...

Asian dust observed during KORUS-AQ facilitates the uptake and incorporation of soluble pollutants during transport to South Korea

, 2020
The air quality of South Korea was the focus of the NASA/NIER KORean -United States Air Quality (KORUS-AQ) mission of 2016. KORUS-AQ was planned for the period after the spring peak in outbreaks of Asian dust.

Airborne cadmium in spring season between Asian dust and non-Asian dust periods in Korea

Atmospheric Environment, 2008
Abstract In an effort to elucidate the environmental significance of the long-range transport of atmospheric pollutants (LRTAP), the particle-bound Cd data for an aerodynamic diameter less than 2.5 (PM2.5) and 10 μm (PM10) fractions were analyzed in the spring periods of four consecutive years between 2001 and 2004.

Relationship between mortality and fine particles during Asian dust, smog–Asian dust, and smog days in Korea

International Journal of Environmental Health Research, 2012
This study examined the association between all-cause/cardiovascular mortality and PM(2.5) as related to Asian dust (AD), smog-AD, smog, and nonevent days and evaluated the differential risks according to specific events for mortality. The daily records of all-cause/cardiovascular mortality and PM(2.5) from March to May 2003-2006 in Seoul, Korea, were ...
