Abstract:

The spectral intensity of ultraviolet radiation from the cloudless and the cloudy sky at Davos Swiss Alps, 1590 m a.s.1. has been measured for lambda330 millimicrons and 370 millimicrons. No effect of atmospheric ozone on the intensity must be taken into account at these wavelengths. The ratio q between the intensity obtained with and without clouds is applied in this investigation as a measure for the influence of the clouds on ultraviolet sky radiation the values of the ratio q have been plotted as a function of solar altitude for various cloud conditions. Mean values q of the ratio q averaged over the whole interval of solar altitude have been determined for different kinds and amounts of cloud and the mean scatter R of the values q has been computed for each cloud condition considered.
