Traditionally the Angstrom turbidity coefficient has been derived from either spectral direct solar radiation measurements or broadband direct solar radiation and precipitable water measurements. The new method for calculating the Angstrom turbidity coefficient presented here is based on the ratio of direct solar radiation to global solar radiation on a horizontal surface and on the `C` model of Iqbal. For this method, it is not necessary to know the precipitable water and the ozone content of the atmosphere. The results of the present model are compared against those of a prior study using experimental data measured at Valencia during 1989-1990. Finally, a graphic method to calculate $beta for any location and standard meteorological conditions is presented. 8 refs., 16 figs., 2 tabs.
