Unprecedented Arctic ozone loss in 2011
Chemical ozone destruction occurs over both polar regions in local winter–spring. In the Antarctic, essentially complete removal of lower-stratospheric ozone currently results in an ozone hole everyExpand

A tropical West Pacific OH minimum and implications for stratospheric composition
Most of the short-lived biogenic and anthropogenic chemical species that are emitted into the atmosphere break down efficiently by reaction with OH and do not reach the stratosphere. Here we show theExpand

Ozone trends at northern mid- and high latitudes - a European perspective
The EU CANDIDOZ project investigated the chemical and dynamical influences on decadal ozone trends focusing on the Northern Hemisphere. High quality long-term ozone data sets, satellite-based as wellExpand

Variability and trends in total and vertically resolved stratospheric ozone based on the CATO ozone data set
Trends in ozone columns and vertical distributions were calculated for the period 1979–2004 based on the ozone data set CATO (Candidoz Assimilated Three-dimensional Ozone) using a multiple linearExpand

On the possible causes of recent increases in northern hemispheric total ozone from a statistical analysis of satellite data from 1979 to 2003
Global total ozone measurements from various satellite instruments such as SBUV, TOMS, and GOME show an increase in zonal mean total ozone at northern hemispheric (NH) mid to high latitudes since theExpand

Ozonesonde observations in the Arctic during 1989–2003: Ozone variability and trends in the lower stratosphere and free troposphere
[1] We have studied the interannual and longer-term variations in ozone profiles over the Arctic from 1989 to 2003 using ozonesonde observations from seven northern high-latitude stations. TheExpand

Uncertainties in modelling heterogeneous chemistry and Arctic ozone depletion in the winter 2009/2010
Abstract. Stratospheric chemistry and denitrification are simulated for the Arctic winter 2009/2010 with the Lagrangian Chemistry and Transport Model ATLAS. A number of sensitivity runs is used toExpand

A quantitative analysis of the reactions involved in stratospheric ozone depletion in the polar vortex core
Abstract. We present a quantitative analysis of the chemical reactions involved in polar ozone depletion in the stratosphere and of the relevant reaction pathways and cycles. While the reactionsExpand

Global wave activity from upper stratosphere to lower thermosphere: A new turbopause concept
Abstract Global temperature measurements are available from CRISTA (CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere) and from SABER (Sounding of the Atmosphere using BroadbandExpand

Relative importance of dynamical and chemical contributions to Arctic wintertime ozone
[1] We present the first complete budget of the interannual variability in Arctic springtime ozone taking into account anthropogenic chemical and natural dynamical processes. For the wintersExpand
