Engineering Physics Annotation << Back On displacement of maximum of spectrum of increment Solar UV radiation caused with variation of total content of ozone in atmosphere upon change of optical air mass R.T. Rajabli In the article the grounding of displacement of maximum of spectrum of sensitivity of ozonometrs in UV band upon various of optical air mass is given. The presence of extremal dependence between ozonometer sensitivity and optical air mass is shown. Key words: Ultraviolet radiation, sensitivity, atmosphere, ozone. E-mail: rroya@yandex.ru.
