Temporal analysis of Sand and Dust Storms (SDS) between the years 2003 and 2017 in the Central Asia

Mineral dust particles play a vital role in climate and the Earth's energy budget and can have impact on weather systems. It has both direct (dust-radiation effect) and indirect (dust-microphysical effect) impacts on the energy budget effect. The most important sources of dust aerosols are loca...
