title: Atmospheric turbidity and the circumsolar radiation.
abstract: We investigate the possibility of determining the turbidity from the intensity of the circumsolar radiation and find that such a connection can be made only when the size distribution of the aerosol particles is known. However, measurements of both the turbidity and the aureole intensity can give useful information about the size distribution.
