Solar ultraviolet irradiance in the ozone hole region in Antarctica
To analyze characteristics of solar ultraviolet irradiance in the ozone hole region, solar ultraviolet-B (UV-B : 280-315nm) and ultraviolet-A (UV-A : 315-400nm) irradiance at noon were measured from October 4,1999 to January 31,2000 at Syowa Station in Antarctica (69°00′S, 39°35′E). UV-B irradiance...
