Abstract:

Since the discovery of Antarctic springtime ozone hole in 1985,there has been much international attention focused on the possible consequences of significant decreases of total ozone. The direct consequences of ozone depletion are the increse in UV B radiation reaching the earth's surface, and the consequential unfavourable changes in ecosystem. Therefore,people have started to pay attention to the observations and researches of UV B radiation over Antarctica,and have constructed progressively Antarctic UV B climatology. In this paper,we review the recent research progress, analyse the problems required further Solution and look forward to the develop.
