Modeling of Ultraviolet Radiation by Regression Analysis

Dr. R. Sumathi


Abstract: In recent years interests of scientific community, general population and international organizations have shifted towards the field of environment safety. Solar UV radiation reaching the Earth’s surface affects the biosphere. In view of the relationship between increased UV levels at the Earth’s surface and depletion of ozone in the stratosphere, significant attention on the level of UV solar radiation on the Earth’s surface has arisen. During the last two decades, there has been increasing interest and activity in the area of ultraviolet (UV) radiation research, evoked by stratospheric ozone depletion [Bais, A. F. , and Lubin, D. , (2007),]. All radiation from the sun travels in the form of electromagnetic waves. The types of solar radiation are characterized in terms of wavelengths. The shortest wavelength radiation (100–280 nm) is referred to as UV C radiation. Radiation at these wavelengths is almost entirely absorbed by atmospheric oxygen, nitrogen and ozone, preventing it from reaching the earth surface. Wavelengths between 280 and 315 nm comprise the UV-B portion of the spectrum. Ultraviolet-B radiation is absorbed mostly but not completely by atmospheric ozone. Wavelengths between 315 and 400 nm are referred to as UV-A radiation. Absorption of UV-A radiation by atmospheric ozone is comparatively small. Although the intensity of solar UV-B radiation is low, the energy per photon is high. Due to this higher energy level, UV-B radiation can have severe harmful impacts on human beings, on ecosystems, and on materials [Webb A. R. , (1998)] [Adam M. E. N. , and El Shazly S. M. , (2007)].
