Abstract
The greatly reduced stratospheric ozone concentrations over the Antarctic continent (popularly known as the Antarctic ozone hole), the consequent increase in short wavelength ultraviolet radiation (UVB), and the influence of this increased UVB on the Antarctic ecosystem has led to the development of new instruments for the measurement of these effects. One instrument, arguably a compromise between a more complex and expensive full spectral narrow-band instrument and a simpler broad-band instrument, is manufactured by Biospherical Instruments (BSI) for the measurement of surface and in-water UV radiation. Here we present preliminary results of direct observations of springtime UVB, using the BSI PUV-510, under the Antarctic ozone hole and provide an algorithm, using the radiative transfer code of Wan, for the accurate estimation of column ozone based upon these measurements. We show that data from the PUV-510 can be used to estimate column ozone, given a rough estimate of surface albedo, to within an accuracy of +/- 10 DU and that this algorithm is robust, working well for both clear and cloudy skies.
