摘要
紫外辐射强度的公众服务一般用紫外线指数来表示 ,是衡量某地正午前后到达地面的太阳紫外辐射对人体皮肤 (或眼睛 )可能损害的程度指标 ,它主要依赖于纬度、季节、平流层臭氧、云况、海拔高度、地面反照率和大气污染状态等条件。紫外线辐射强度的观测主要使用紫外光谱辐射计与滤光片式的紫外辐射表。
The ultraviolet radiation for the public service usually abbreviated UVI, is to express the index as the solar noon erythemally weighted dose rate. UVI mainly depends on latitude, season, stratospheric ozone field, cloud amount, height above sea level, SO 2 and aerosols et.al. Observation of surface sunny ultraviolet radiation is mainly done by the UV spectroradiometer and filter ultraviolet radiation meter.
