Power-law correlations in column ozone over Antarctica
Detrended fluctuation analysis is applied on springtime daily column ozone at the edge and into the Antarctic ozone hole, by using observations deduced from ground-based (1972-2003) and satellite-borne instrumentation (1979-2003). First, extreme column ozone fluctuations obey a power-law with expone...

Detrended fluctuation analysis is applied on springtime daily column ozone at the edge and into the Antarctic ozone hole, by using observations deduced from ground-based (1972-2003) and satellite-borne instrumentation (1979-2003).
