Sensitivity of stratospheric Bry to uncertainties in very short lived substance emissions and atmospheric transport
stratospheric Bry lived substance emissions atmospheric transport
2011/2/25
We evaluate the sensitivity of Bry entering the stratosphere with a simplified model that allows calculations over a wide parameter range for parameters that are currently poorly quantified. The model...
Evaluation of stratospheric chlorine chemistry for the Arctic spring 2005 using modelled and measured OClO column densities
stratospheric chlorine chemistry the Arctic spring 2005 OClO column densities
2011/2/24
Chlorine dioxide, OClO, column amounts retrieved from measurements of the SCIAMACHY satellite instrument are presented and validated by comparison with simultaneous ground-based DOAS observations. In ...
Attribution of observed changes in stratospheric ozone and temperature
observed changes stratospheric ozone temperature
2011/2/24
Three recently-completed sets of simulations of multiple chemistry-climate models with greenhouse gases only, with all anthropogenic forcings, and with anthropogenic and natural forcings, allow the ca...
Analysis of a rapid increase of stratospheric ozone during late austral summer 2008 over Kerguelen (49.4° S, 70.3° E)
stratospheric ozone late austral summer 2008 Kerguelen (49.4° S, 70.3° E)
2011/1/19
This paper reports on an increase of ozone event observed over Kerguelen (49.4° S, 70.3° E) in relationship with large-scale isentropic transport. This is evidenced by ground-based observations (co-lo...
Attribution of stratospheric ozone trends to chemistry and transport: a modelling study
stratospheric ozone chemistry transport a modelling study
2010/12/28
The decrease of the concentration of ozone depleting substances (ODSs) in the stratosphere over the past decade raises the question to what extent observed changes in stratospheric ozone over this per...
Spatial, temporal, and vertical variability of polar stratospheric ozone loss in the Arctic winters 2004/2005–2009/2010
polar stratospheric ozone the Arctic winters
2010/10/21
The polar stratospheric ozone loss during the Arctic winters 2004/2005–2009/2010 is investigated by using high resolution simulations from the chemical transport model Mimosa-Chim and observations fro...
The potential to narrow uncertainty in projections of stratospheric ozone over the 21st century
stratospheric ozone the 21st century
2010/10/11
Future stratospheric ozone concentrations will be determined both by changes in the concentration of ozone depleting substances (ODSs) and by changes in stratospheric and tropospheric climate, includi...
Multi-model assessment of stratospheric ozone return dates and ozone recovery in CCMVal-2 models
stratospheric ozone return dates ozone recovery CCMVal-2 models
2010/10/11
Projections of stratospheric ozone from a suite of chemistry-climate models (CCMs) have been analyzed. In addition to a reference simulation where anthropogenic halogenated ozone depleting substances ...
Response of tropical stratospheric O3, NO2 and NO3 to the equatorial Quasi-Biennial Oscillation and to temperature as seen from GOMOS/ENVISAT
tropical stratospheric O3, NO2 and NO3 the equatorial Quasi-Biennial Oscillation temperature GOMOS/ENVISAT
2010/9/21
Quasi-Biennial Oscillation signals can be found in the evolution of the three constituents up to at least 40 km. We found that NO3 is positively correlated with temperature up to 45 km in the region w...
Quantifying the contributions to stratospheric ozone changes from ozone depleting substances and greenhouse gases

A state-of-the-art chemistry climate model coupled to a three-dimensional ocean model is used to produce three experiments, all seamlessly covering the period 1950–2100, forced by different combinatio...
A closer look at Arctic ozone loss and polar stratospheric clouds
Arctic ozone loss polar stratospheric clouds
2010/9/21
The empirical relationship found between column-integrated Arctic ozone loss and the potential volume of polar stratospheric clouds inferred from meteorological analyses is recalculated in a self-cons...
Stratospheric water vapour budget and convection overshooting the tropopause: modelling study from SCOUT-AMMA
Stratospheric water vapour the tropopause SCOUT-AMMA
2010/9/14
The aim of this paper is to study the impacts of overshooting convection at a local scale on the water distribution in the tropical UTLS. Overshooting convection is assumed to be one of the processes ...
Optical extinction by upper tropospheric/stratospheric aerosols and clouds: GOMOS observations for the period 2002–2008
upper tropospheric/stratospheric aerosols and clouds GOMOS observations the period 2002–2008
2010/9/1
Although the retrieval of aerosol extinction coefficients from satellite remote measurements is notoriously difficult (in comparison with gaseous species) due to the lack of typical spectral signature...
Stratospheric water vapour and high climate sensitivity in a version of the HadSM3 climate model
