Spectral measurements of global solar irradiance, obtained under cloud-free conditions during the SUSPEN campaign (July 1997) in Thessaloniki, Greece are compared with radiative transfer model calculations, showing an agreement to within ± 5% for wavelengths higher that 305nm. The uncertainties in the modeled spectra were analyzed with respect to the aerosol-related model input parameters (single-scattering albedo and asymmetry factor), which were not derivable from measurements. A range of single-scattering albedo values was used to investigate its impact on surface UV irradiance, through comparison of measurements with model calculations. It was found that a difference in the single-scattering albedo of 0.1 changes the model-to-measurement ratio by 7-14%, depending on solar zenith angle. Finally, an attempt was made to relate the estimated values of single-scattering albedo to wind direction and relative humidity, which control the origin and type of the aerosols in the area. | [keywords]
