| Notes: (1) Parameter deprecated - See Regulation 92.6.2 and use another parameter instead. (2) The Global Solar UVI is formulated using the International Commission on Illumination (CIE) reference action spectrum for UV-induced erythema on the human skin (ISO17166:1999/CIE S 007/E-1998). It is a measure of the UV radiation that is relevant to and defined for a horizontal surface. The UVI is a unitless quantity defined by the formula: (3) Normal flux is on a surface lifted to be normal to sun rays. |
