Abstract:

Formulas are derived for volume scattering coefficients applicable to aerosols. Different types of size distribution for the aerosol, such as normal distribution, log-normal distribution, and exponential distribution, are assumed. Nominal results obtained by the author and those published in the literature are given and discussed. The volume scattering coefficients become smooth functions. The size distribution is very wide. Hence, simpler mathematical formulation can be used than those obtained from the exact Mie theory. However, only the number of aerosol particles can be obtained from an evaluation of experimental data, but details of the size distribution cannot be extracted from experimental data.
