A simple formula is developed in this paper for the relative annual damaging ultraviolet radiation DUV dose at different tropical and mid-latitude sites. The formula consists of six multiplicative factors which include the effects of amount of ozone, latitude, altitude, cloudiness, ground albedo, and amount of aerosols. A seasonal ozone variation factor is introduced to modify the tropical relative DUV formula for application to mid-latitude sites. The approach involves correlations of sometimes sparse data, and remains to be validated in the general sense. The formula should be useful, where more exact data are not available, in studies of the effects of solar ultraviolet radiation--and its possible increase from a reduction in stratospheric ozone--on land and marine ecological systems and skin cancer incidence in white Caucasian populations.
