Abstract

Direct solar radiation intensity was measured with an Eppley sun photometer at 380 and 500 nm near Page, Ariz. The turbidity coefficient B derived from these measurements was anomalous, B 380 < B 500. This unusual condition seems to be caused by a combination of an appreciable amount of water vapor in very clean tropospheric air plus an almost monodisperse stratospheric aerosol. We recommend the inclusion of a water vapor term in the basic turbidity equation.
