BACKGROUND Dust accumulation on surfaces of critical instruments has been a major concern during lunar and Mars missions. Operation of instruments such as solar panels, chromatic calibration targets, as well as Extra Vehicular Activity (EVA) suits has been severely compromised in the past as a result of dust accumulation and adhesion. Wind storms with wind speeds of up to 70 mph have not been e...

background: the phenomenon of dust is a serious environmental problem in dry and semi dry regions. it has a destructive effect for the residents of such regions. over two-thirds of iran is in areas of dry and semi-dry climate conditions. methods: in this research, dust fall measurements were taken in 41 stations across yazd city using a marble dust collector (mdco) located in different parts of...

Dust storms are of interest to study since they are correlated to an increase in mortality rates due to respiratory illness especially in the south-western U.S. With the aim of providing better tools to the understanding of dust storms, we present models for detection of dust storms from MODIS Terra Level 1B radiances, which can be applied in near real time with 1km resolution, in contrast to t...

Owing to recent climate changes, dust storms are increasingly common, particularly in the Middle East region. Dust accumulation and subsequent mud formation on solid surfaces in humid environments typically have adverse effects on surface properties such as optical transmittance, surface texture, and microhardness. This is usually because the mud, which contains alkaline and ionic species, adhe...

Dust storm occurs frequently in arid and semi-arid areas of the world. This natural phenomenon, which is the result of stormy winds, raises a lot of dust from desert surfaces and decreases visibility to less than 1 km. In recent years the temporal frequency of occurrences and their spatial extents has been dramatically increased. West of Iran, especially in spring and summer, suffers from signi...

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...

Extratropical cyclones have attracted some attention in climate policy circles as a possible significant damage factor of climate change. This study conducts an assessment of economic impacts of increased storm activities under climate change with the integrated assessment model FUND 3.4. In the base case, the direct economic damage of enhanced storms due to climate change amounts to $2.4 billi...
