Mineral dust emission accounts for a substantial portion of particles present in the troposphere. It is emitted mostly from desert areas, mainly through intense storm episodes. The aim of this work was to quantify sizesegregated fluxes of mineral dust particles emitted during storm events occurring in desert areas of northern China (Alashan desert, Inner Mongolia), known to act as one of the st...

Water scarcity is one of the factors limiting plant growth and development. More than onethird of the global terrestrial ecosystems is located in arid and semi-arid regions. The mostimportant limiting factor for plant growth is water shortage. Drought could significantlychange the natural vegetation cover. Rainfall reduction in Iraq, Turkey and Syria hasreduced vegetation cover so that dust sto...

The impact of a typical pre-monsoon season (April–June) dust storm event on the regional aerosol optical properties and radiation budget in northern India is analyzed. The dust storm event lasted from 17 to 22 April 2010 and the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) estimated total dust emissions of 7.5 Tg over the model domain. Both in situ (AERONET – Aerosol...

1. introduction dust storm is an important atmospheric phenomenon. it has important environment, health, economic and social activities due to penetration of suspended particles of dust to the atmosphere. measurements resulting from earth and satellite stations show the fact that particles of dust in storms, remain in the nature for a long time. they can get far away by wind, hundreds of kilome...

Sand and dust storms are natural events that occur widely around the world, mostly in dry and bare lands. Over thepast decade a large part of Iran has been affected by this phenomenon, and Tehran has not been excluded from thisevent. Therefore, having knowledge of spatiotemporal frequency variations can aid us in future management andstorm trajectory assessment. In this study the synoptic anemo...

The vast expanse of the Gobi desert across the Mongolian plateau features frequent dust storms. In this isolated region remote sensing techniques can provide an effective measurement of dust storms. Brightness temperature channels 4, 5 of AVHRR/NOAA satellite data, emissive bands of MODIS/TERRA satellite data, and meteorological station measurement data were used and tested for dust and sandsto...

In this study, data provided by the geostationary satellite GMS-5 S-VISSR was used to monitor dust storms. Although other satellites, such as TOMS, provide information regarding dust cover and air quality over specific locations, their limited orbital observation time makes it hard to issue real-time warnings for dust storms. Since geostationary satellites are capable of providing hourly observ...

The three typical extreme weather of fog, haze and dust storm have occurred frequently in recent years in 10 China. These events influence the transportation, the ecological environment, and the daily lives of people. Remote sensing is very important technology that can be used to monitor them due to its high temporal resolution and wide area of coverage. But because the spectral features of th...
