Asian dust events of April 1998

Journal of Geophysical Research: Atmospheres, 2001
On April 15 and 19, 1998, two intense dust storms were generated over the Gobi desert by springtime low‐pressure systems descending from the northwest. The windblown dust was detected and its evolution followed by its yellow color on SeaWiFS satellite images, routine surface‐based monitoring, and through serendipitous observations.

Contrasting synoptic weather patterns between non-dust high particulate matter events and Asian dust events in Seoul, South Korea

Atmospheric Environment, 2019
The serious degradation of regional air quality is a critical social issue in East Asia despite continuous efforts to reduce the emission of pollutants and their precursors.

Asian Dust: Seasonal Transport to the Hawaiian Islands

Science, 1983
Analyses of atmospheric particles collected at Mauna Loa Observatory in Hawaii from February 1979 through September 1982 reveal strong influxes of Asian dust in the spring of each year. Concentrations of a typical crustal element, aluminum, are more than an order of magnitude greater between February and June than during the remainder of the year (71 ±

Airborne Asian sand dust enhances murine lung eosinophilia

Inhalation Toxicology, 2010
There is no experimental study demonstrating the effects of airborne Asian sand dust (AASD) on allergic lung eosinophilia. The organic substances adsorbed onto AASD collected from the atmosphere of Iki-island in Japan were excluded by heat treatment at 360°C for 30 min. The effects of AASD or heated-AASD (H-AASD) towards allergic lung inflammation were

Prediction skill of Asian Dust Generation in hindcast data of Asian Dust Seasonal Forecasting Model (GloSea5-ADAM)

2023
This study investigated the prediction skill of the Asian dust seasonal forecasting model (GloSea5-ADAM) on the Asian dust and meteorological variables related to the dust generation using hindcasts of GloSea5-ADAM for the period of 1991~2016 for East Asia.

An enhanced dust index for Asian dust detection with MODIS images

International Journal of Remote Sensing, 2013
An enhanced dust index EDI for Moderate Resolution Imaging Spectroradiometer MODIS solar reflectance bands is proposed that provides a means to detect the dust status of the atmosphere. The EDI utilizes only solar reflectance channels and may therefore be applied consistently to the entire MODIS time series records 1999 to present for daytime dust ...

Asian dust signatures at Barrow: observed and simulated. Incursions and impact of Asian dust over Northern Alaska

IEEE Workshop on Remote Sensing of Atmospheric Aerosols, 2005., 2005
Atmospheric aerosols affect the Earth's radiation budget both directly, through interactions with solar and terrestrial radiation, and indirectly, as cloud condensation and ice nuclei. Against the typically clean polar atmospheres, small increases in aerosol concentrations can perturb radiative fluxes significantly. During spring 2002, dust storms from

Effects of Asian dust events on atmospheric bacterial communities at different distances downwind of the source region.

Journal of Environmental Science, 2018
Aeolian dust particles arising from arid and semiarid zones are known to carry microbes by air currents. The effect of wind-borne bacteria on atmospheric bacterial population at various downwind distances from the dust source regions must be clarified ...

Quantitative classification of northeast Asian dust events

Journal of Geophysical Research: Atmospheres, 2007
In this paper, we introduce a quantitative classification of dust events on the basis of dust, PM10 concentration, and wind speed for northeast Asia. The empirical relationship between visibility and PM10 concentration is established by regression of visibility and PM10 concentration that were taken every 5 min at 11 sites in the spring of 2004 and ...
