** The Global Solar UVI is formulated using the International Commission on Illumination (CIE)
reference action spectrum for UV-induced erythema on the human skin (ISO 17166:1999/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:
