【摘要】 近10多年来,随着人类居住环境的恶化,紫外线给人类造成了巨大的伤害。利用潍坊市气象台2004~2006年逐日紫外线观测资料,分析了太阳紫外线辐射到达地面的强度指数和等级,同时分析了这些量的年、月、日变化特征,研究了影响紫外线辐射的主要的几种因子。影响紫外线辐射强度的主要因素是臭氧、地表反射率、大气气溶胶和云,这些影响因素的变化对太阳紫外线到达地面的辐射起着举足轻重的作用。更多还原

【Abstract】 In recent 10 or more years,with worsening of the humanity environment,the ultraviolet ray have caused great damage to the human being. By use of daily data of ultraviolet ray recorded at Weifang Meteorological Observatory from 2004 to 2006,intensity exponent and grade of sun ultraviolet radiation getting to the ground surface are analyzed.The characteristics of annual,monthly and diurnal changes of these quantities are analyzed.At the same time,the main factors affecting ultraviolet radiation are studied.The main factors affecting ultraviolet ray radiation intensity are ozone,the earth’s surface reflectivity,aerosols and cloud.The changes of these factors play an important role in solar ultraviolet ray radiation to the ground surface.更多还原
