Gonzalo G. Ysasi and Luis J. C. Ribera Analysis of Two Kinds of Tree as Physical Barriers Against Erythemal UVB Radiation Received Photochemistry and Photobiology 89
Differences between global radiation UVER (erythemal ultraviolet solar radiation) received under full sun and diffuse radiation received under the shadow of two types of tree are analyzed in order to check the importance of these components on human exposure to UV radiation. Measurements were obtained in relatively clear days from February to December 2009. Values of UVER in full sun and under the shadow of Pine and Sauce, were obtained. Finally, average daily irradiance received under the shadow of each tree in comparison with those received in full sun, was also analyzed.
