Abstract

Spectral ultraviolet measurements in the wavelength range 290 to 325 nm made at Sodankyla (67.4 degree(s)N, 26.6 degree(s)E) in 1990 - 1992 were used to study the effects of surface albedo, atmospheric total ozone, and atmospheric aerosol content on UV irradiance on the surface of the Earth. Clear sky observations with optical air masses 1.4 and 2.0 were used in the analysis. The annual course of surface albedo between 0.1 and 0.8 was found to be responsible for a change of 10% in irradiance at 325 nm, but no effect was seen at lower wavelengths or in CIE-weighted integrated values.
