ARPANSA maintains a network of broadband solar UV dataloggers in major Australian population centres, all of which are currently at or near to sea level. However solar UV levels are known to increase with altitude (Blumthaler et al., 1997, McKenzie et al., 2001).
Most previous studies on the altitude effect have been conducted in the Northern hemisphere and to our knowledge no spectral investigation has been completed under Australian conditions. ARPANSA is currently undertaking an investigation of the effects of altitude on the measured solar UV spectrum at various sites in the state of Victoria, Australia.
Results from this study will be used to help validate the models used for the Cancer Council’s SunSmart UV Alert programme.
