Ultraviolet Radiation and the Terrestrial Surface
Abstract
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.
