The Antarctica 'Ozone Hole' was discovered in 1985 by Farman’s group When theystudied the history （from 1957 to 1984） records of total ozone column abundance at HalleyBay（75.5°S,26.3°W） Station. Later, observations from TOMS also confirmed the factthat the ozone depletion did happen over the Antarctica continent during the Australspring.Since then, more intensive research programs have been performed by somecountries such as the USA, Britain, Japan at their stations in Antarctica.

The Antarctica ''Ozone Hole'' was discovered in 1985 by Farman's group when they studied the history (from 1957 to 1984) records of total ozone column abundance at Halley Bay (75.5 degrees S, 26.3 degrees W) Station([1]). Later, observations from TOMS also confirmed the fact that the ozone depletion did happen over the Antarctica continent during the Austral spring([2]). Since then, more intensive research programs have been performed by some countries such as the USA, Britain, Japan at their stations in Antarctica. The first research of China in this field has been done with the work of measurements of O-3, UV-B and NO, by using a Brewer ozone-spectrophotometer (#074) at Chinese Zhongshan Station (69.38 degrees S, 76.3 degrees E) during the 9th CHINARE program (1992 - 1993). The data of total column ozone abundance from the Brewer, being a comparison with the TOVS data, and the dose rate of noontime biologically UV-B (290 - 325 nm) radiation at Zhongshan Station are presented in this note. Furthermore, consulting the WMO Antarctica Ozone Bulletin, an outline of the 93 ''Ozone Hole'' and its impact on enhancing the penetration of UV-B radiation at Zhongshan Station is also presented.
