Extreme events in total ozone over Arosa – Part 2: Fingerprints of atmospheric dynamics and chemistry and effects on mean values and long-term changes
Extreme events total ozone Arosa atmospheric dynamics and chemistry and effects mean values long-term changes
2010/11/3
In this study the frequency of days with extreme low (termed ELOs) and extreme high (termed EHOs) total ozone values and their influence on mean values and trends are analyzed for the world's longest ...
Extreme events in total ozone over Arosa – Part 1: Application of extreme value theory
Extreme events total ozone Arosa extreme value theory
2010/11/3
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 ...
Total ozone time series analysis:a neural network model approach
Total ozone time series analysis neural network model approach
2009/11/11
This work is focused on the application of neural network based models to the analysis of total ozone (TO) time series. Processes that affect total ozone are extremely non linear, especially at the co...
Long-range correlations of extrapolar total ozone are determined by the global atmospheric circulation
Long-range correlations extrapolar total ozone global atmospheric circulation
2009/11/3
TOMS (Version 8) ozone records are analysed between latitudes 60° S and 60° N, in order to extract autocorrelation properties with high spatial resolution. After the removal of semi-annual, annual, an...
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...
Six years of total ozone column measurements from SCIAMACHY nadir observations
Six years total ozone column measurements SCIAMACHY nadir observations
2010/2/8
Total O3 columns have been retrieved from six years of SCIAMACHY nadir UV radiance measurements using SDOAS, an adaptation of the GDOAS algorithm previously developed at BIRA-IASB for the GOME instrum...
Comparison of total ozone from the satellite instruments GOME and TOMS with measurements from the Dobson network 1996–2000
ozone GOME TOMS Dobson
2009/3/11
Over the last 3 decades, satellite data have been used to monitor long-term global changes in stratospheric ozone. The TOMS series (1978-present) and GOME (1995-present) are two very important instrum...
Fall vortex ozone as a predictor of springtime total ozone at high northern latitudes
Fall vortex ozone springtime total ozone high northern latitudes
2009/2/11
Understanding the impact of atmospheric dynamical variability on observed changes in stratospheric O3 is a key to understanding how O3 will change with future climate dynamics and trace gas abundances...

A new algorithm approach called Weighting Function Differential Optical Absorption Spectroscopy (WFDOAS) is presented which has been developed to retrieve total ozone columns from nadir observations ...
The total ozone field separated into meteorological regimes – Part II: Northern Hemisphere mid-latitude total ozone trends
total ozone field meteorological regimes Northern Hemisphere mid-latitude ozone trends
2009/1/19
Previous studies have presented clear evidence that the Northern Hemisphere total ozone field can be separated into distinct regimes (tropical, midlatitude, polar, and arctic) the boundaries of which ...
