Comparison of biologically damaging spectral solar ultraviolet radiation at a southern hemisphere sub-tropical site

Parisi, Alfio V., Sabburg, Jeff M., & Kimlin, Michael G. (2003) Comparison of biologically damaging spectral solar ultraviolet radiation at a southern hemisphere sub-tropical site. Physics in Medicine and Biology, 48, N121-N129.


The first dataset of a complete year of biologically damaging spectral UV at a sub-tropical latitude in the southern hemisphere has been presented. The new data provides a baseline dataset against which comparisons can be made in the future to establish if there have been any long term trends in the biologically damaging UV. The general shape of the variation of the daily biologically damaging exposures through the year depends on the relative response of the various action spectra at the different wavelengths. The ratio of the daily erythemal to actinic exposures drops by approximately 20 to 25% from winter to summer. The ratio of the erythemal to DNA exposures drops by approximately 50% over the same period. In contrast, the ratio of the erythemal to plant damage exposures is higher in summer compared to winter. This is due to the changes in the relative proportion of UVA to UVB wavebands and relative responses of the different action spectra. The relative changes for the different action spectra show that the erythemal action spectrum cannot be used as a proxy for other biologically damaging responses.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
