Atmospheric Aerosol Optical Properties and Climate Change in Arid and Semi-Arid Regions

Study analyzing ground measured aerosol optical thickness, angstrom exponent and size distribution data obtained from AERONET (Aerosol Robotic Network), Sun-photometer site at arid region of Mongolia in order to characterize aerosol optical properties

Topic:

Climate Change; Drought; Migration

Details:

The sturdy analyzed ground measured aerosol optical thickness, angstrom exponent and size distribution data obtained from AERONET (Aerosol Robotic Network), Sun-photometer site at arid region of Mongolia in order to characterize aerosol optical properties. The result shows; spring and early summer has the highest seasonal average AOT (Aerosol Optical Thickness) and minimum seasonal average appears in winter and mean monthly Angstrom exponent values occurred mostly in the range 1.0-1.93. However, low values of Angstrom exponent appears within the range 0.58-0.76 in spring. Hence, average monthly Angstrom exponents indicate that aerosol mixtures of both coarse and fine mode particles, especially dust aerosols are dominant in spring (March, April).
