Atmospheric Turbidity

Turbidity, Atmospheric

 

the reduction in the transparency of air resulting both from the scattering of light by tiny particles suspended in the air (water droplets, ice crystallites, and dust and smoke particles) and from the absorption of light by water vapor. Increasing atmospheric turbidity is accompanied by increasing scattering of solar rays and decreasing intensity of direct solar radiation. The turbidity factor is a quantitative characterization of atmospheric turbidity.

Aerosol optical depth, AOD[lambda], is a central parameter for the description of column aerosol content and column optical properties, including the rate of atmospheric turbidity. From the 1990s, after the start of the US NASA programmes AERONET, TerraMODIS, and AquaMODIS, this parameter became available and very popular (Holben et al., 1998; Toledano et al., 2007).

The effect of reduced economic activity around the Great Depression also appears to have temporarily resulted in reduced atmospheric turbidity and, therefore, enhanced counts of sunny days.

For very clear atmospheric conditions (AOT500 < 0.2) the method never predicted unnatural negative values, which sometimes occurs in modelling the AOT under extremely low atmospheric turbidity conditions (Gueymard, 1998).
