Theoretical clear day UV dose to horizontal and vertical surfaces, for Arctic Finland
Sources Title (cont.) The amount of energy from UV radiation reaching a horizontal surface peaks around midsummer, while that reaching a vertical surface peaks in early spring, in part due to efficient reflection by snow. The irregular line shows the results obtained by using measured values for total ozone. The smooth lines were calculated with the mean (climatological) total ozone. The dashed line depicts the mean vertical exposure with summer albedo (0.04). The theoretical curves are realistic only for clear skies with fresh snow. (AAR Figure 11.20)
