Light scattering by atmospheric aerosols modifies the diffuse and direct solar radiation observed at the Earth’s surface as well as from spaceborne radiometers. When the atmospheric characteristics are known, including the vertical distribution of aerosols and their optical and microphysical properties, the diffuse radiation field can be computed using the methods outlined in Chapter 3. Ground-based measurements of diffuse and direct solar radiation have been used to infer the size distribution of aerosol particles in the intervening atmosphere as well as their optical properties. This is often accomplished by comparing measurements with computations for a wide range of aerosol parameters. This method is referred to as look-up table procedures whereby a solution is obtained by comparing measurements with theoretical calculations.
