Australian UV-Index ModelsThe UV-Index model is an indication of the maximum daily level of ultraviolet radiation (UVR) expected at ground level on a cloudless day. ARPANSA calculates the models for each site using a computer modelling program that considers, among other parameters, the time of year and estimated ozone values.
The graph displays the monthly average UV-Index value that can be expected at solar noon (when the sun is highest in the sky) at this location. The actual value could be slightly higher or lower depending on ozone levels and atmospheric conditions, particularly cloud cover.
