Available in PDF, EPUB and Kindle. Book excerpt: Although variations in the intensity of solar ultraviolet irradiation of the Earth's surface may provide significant opportunities for observation in the ultraviolet spectrum, research in the ultraviolet region has been neglected by terrestrial scientists. The spectral properties of vegetation and soils and of undisturbed weathered natural surfaces of rocks and sediments, in situ, are unknown. Limited spectrophotometric data obtained in the laboratory, but of samples removed from their environment, indicate that there may be less distinctive spectral character in the ultraviolet than at the longer wavelengths. Spectral reconnaissance studies in the near-ultraviolet region are therefore warranted.

This book was released on 2006-06-30 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the history of science the opening up of a new observational or experimental window is always followed by an increase in knowledge of the subject concerned. This is also the case with the subject of this book, ultraviolet radiation (hereafter UV). In principle, the ultraviolet range might be just one more of these windows, of no particular importance. However, the energy per UV photon provides the main peculiarity, its magnitude being great enough to produce important ch- ical reactions in the atmospheres of planets and satellites, thereby a?ecting the transmission of this radiation to the ground. The Sun is the main natural source of UV radiation in the Solar System and our planet is the body where its in?uences can be best tested and the only one where its relation with life can be studied. However, the terrestrial atmosphere blocksmostofthephotonsinthiselectromagneticrangeandastronomershavehad to develop various techniques (balloons, planes and rockets) to cross this barrier and access the information. These tools have been used in parallel to investigate the physical properties of the terrestrial atmosphere and the interaction of its constituents with light. This book will addresses most of these topics.

Download or read book UV Radiation and Arctic Ecosystems written by D.O. Hessen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are some biological processes that are supported by UV radiation, most organisms are stressed by it in various ways, e.g. through DNA damage. Top international experts present an integrated overview of UV radiation and its effects on terrestrial, freshwater and marine Arctic biota. Increased stratospheric ozone depletion and the corresponding increase in ground levels of UV radiation as well as ambient, "natural" UV radiation as a key ecological factor in the Arctic spring and summer are discussed in detail. Additionally, basic information on Arctic ecosystems is given. The volume provides not only an excellent account of present-day knowledge of the subject, but also describes the state of the art on which future research can be built.
