Diffuse Component of the Solar Ultraviolet Radiation in Tree Shade

This paper has provided the first set of quantitative data of diffuse erythemal UV and UVA in tree shade at a sub-tropical Southern Hemisphere latitude. Over the summer, approximately 60% of the erythemal UV radiation in the tree shade is due to the diffuse component. Similarly, approximately 56% of the UVA radiation in the tree shade is due to the diffuse component. In the tree shade these dif...

Effects of tree shade on solar ultraviolet exposures to humans

This paper investigates how much solar UV protection is provided by the shade of Australian trees and the anatomical distribution of personal UV exposures in the shade of these trees. Personal UV exposures in tree shade are of a high enough value to require additional UV reduction strategies. A well planned strategy using a combination of protective methods can minimize the level of exposure to...

palaeovolcanos, solar activity and pine tree-rings from the kola peninsula (northwestern russia) over the last 560 years

the paper deals with the analysis of the external factor (solar activity, volcanic eruptions) influence on tree growth at the kola peninsula, northwestern russia. pinus sylvestris l. (scots pine) tree-ring chronologies collected nearby the northern timberline (68.63n, 33.25e) include the oldest (1445-2005 ad) living pine tree found up to date in the kola peninsula. a total of 18 living trees pi...
