A generally accepted value for the Radiation Amplification Factor (RAF), with respect to the erythemal action spectrum for sunburn of human skin, is -1.1, indicating that a 1.0% increase in stratospheric ozone leads to a 1.1% decrease in the biologically damaging UV radiation in the erythemal action spectrum reaching the Earth. The RAF is used to quantify the non-linear change in the biologically damaging UV radiation in the erythemal action spectrum as a function of total column ozone (O). Spectrophotometer measurements recorded at ten US monitoring sites were used in this analysis, and over 71,000 total UVR measurement scans of the sky were collected at those 10 sites between 1998 and 2000 to assess the RAF value. This UVR dataset was examined to determine the specific impact of clouds on the RAF. Five de novo modeling approaches were used on the dataset, and the calculated RAF values ranged from a low of -0.80 to a high of -1.38.
相对于人类皮肤晒伤的红斑作用光谱，辐射放大因子（RAF）的普遍接受值为-1.1，这表明平流层臭氧增加1.0%会导致到达地球的红斑作用光谱中具有生物损伤性的紫外线辐射减少1.1%。RAF用于量化红斑作用光谱中具有生物损伤性的紫外线辐射随总臭氧柱（O）的非线性变化。本分析使用了在美国十个监测站点记录的分光光度计测量数据，在1998年至2000年期间，在这10个站点收集了超过71000次对天空的总紫外线辐射测量扫描数据，以评估RAF值。对该紫外线辐射数据集进行了检查，以确定云层对RAF的具体影响。对该数据集使用了五种全新的建模方法，计算出的RAF值范围从低至-0.80到高至-1.38。
