Scattering Power Law Distributions

Aerosol size distributions can sometimes be represented by a power law relationship in the size subrange 0,1 3 /zm, where most of the comribution to light scattering occurs  

Suchdistnbution.s are often used to represent atmospheric and clean room aerosols. Equation (5.26) can be written without loss of generality in terms of the average particle diameter 

Substituting (5.27) in the expression for the scattering part of the extinction coefficient, (5.16), we obtain 

II is also foLind expersmen tally that the dependence of h -u on for the atmospheric aerosol can sometimes be represented by an equation of the form
