In this study ideas from extreme value theory are for the first time applied in the field of stratospheric ozone research, because statistical analysis showed that previously used concepts assuming a ...
A model study of the January 2006 low total ozone episode over Western Europe and comparison with ozone sonde data
low total ozone episode Western Europe ozone sonde data
2009/9/11
Total column and stratospheric ozone levels at mid-latitudes often reveal strong fluctuations on time scales of days caused by dynamic processes. In some cases the total ozone column is distinctly red...
Comparison of total ozone from the satellite instruments GOME and TOMS with measurements from the Dobson network 1996–2000
