Aerosols in Astrophysics

Using MODIS data for nonlinear hazard analysis of the Middle East aerosols

Aerosols are among the most important of atmospheric pollutants observed like the microscopic particulate matter in the lower parts of the troposphere. The main purpose of this study is introducing a new method based on satellite images processing results and nonlinear analysis (fractal based) to investigate the origin and dynamical mechanism of aerosols distribution in North Africa and the Mid...

Dust Particles and Aerosols: Impact on Biota “A Review” (Part III)

Natural resources play a fundamental role in the economy of country and create the situation to achieve the goals of sustainable society, these valuable resources have to be conserved  and used with care. Destroying the forests and rangelands will lead to a dark future full of poverty, starvation and environmental pollution. Forests and rangelands play a considerable role in reducing air pollut...

Design, construction and calibration of single channel sun-photometer for study of aerosols

Aerosols are tiny liquid or solid particles suspended in the air have a strong influence on air quality, human health and climate change. Sun-photometer is a tool for measuring the optical and physical characteristics of aerosols by using sunlight at various wavelengths from the Earth surface. In this paper, the design, construction, and calibration of a single channel sun-photometer is present...

Seismology of solar spicules based on Hinode/SOT observations

شناسایی منشا ذرات معلق در اتمسفر با استفاده از ویژگی‌های ژئوشیمیایی عناصر ردیاب (مطالعه موردی: شهر کرمانشاه)

The purpose of this research was source identification of aerosols in atmosphere using geochemical properties in the city of Kermanshah. The concentrations of twenty elements consisting of K, Na, Ca, P, Cu, Ni, Pb, Cd, Se, Zn, Fe, Mg, B, Cr, Co, As, Mo, V were analyzed by ICP for 55 soil samples (in the height range of 600-1600m) and 41 aerosols samples. Source identification of aerosels using ...
