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...
Validation of Ozone Monitoring Instrument (OMI) ozone profiles and stratospheric ozone columns with Microwave Limb Sounder (MLS) measurements
Ozone Monitoring Instrument ozone profiles stratospheric ozone columns Microwave Limb Sounder measurements
2010/3/16
We validate OMI ozone profiles between 0.22–215 hPa and stratospheric ozone columns down to 215 hPa (SOC215) against v2.2 MLS data from 2006. The validation demonstrates convincingly that SOC can be d...
Sensitivity of polar stratospheric ozone loss to uncertainties in chemical reaction kinetics
polar stratospheric ozone uncertainties chemical reaction kinetics
2009/11/19
The impact and significance of uncertainties in model calculations of stratospheric ozone loss resulting from known uncertainty in chemical kinetics parameters is evaluated in trajectory chemistry sim...
Evolution of stratospheric ozone and water vapour time series studied with satellite measurements
stratospheric ozone water vapour time series satellite measurements
2009/8/25
The long term evolution of stratospheric ozone and water vapour has been investigated by extending satellite time series to April 2008. For ozone, we examine monthly average ozone values from various ...
The contribution of anthropogenic bromine emissions to past stratospheric ozone trends: a modelling study
anthropogenic bromine emissions stratospheric ozone trends modelling study
2009/5/6
Bromine compounds play an important role in the depletion of stratospheric ozone. We have calculated the changes in stratospheric ozone in response to changes in the halogen loading over the past deca...
Vertical and latitudinal changes in the stratospheric ozone in the post-chlorofluorocarbon (CFC) era are investigated using simulations of the recent past and the 21st century with a coupled chemistry...
Evolution of stratospheric ozone during winter 2002/2003 as observed by a ground-based millimetre wave radiometer at Kiruna, Sweden
stratospheric ozone ground-based millimetre wave radiometer Kiruna
2009/2/10
We present ozone measurements from the millimetre wave radiometer installed at the Swedish Institute of Space Physics (Institutet för rymdfysik, IRF) in Kiruna (67.8° N, 20.4° E, 420 m asl). Near...
Simulation of stratospheric water vapor trends: impact on stratospheric ozone chemistry
stratospheric water vapor trends stratospheric ozone chemistry
2009/2/9
A transient model simulation of the 40-year time period 1960 to 1999 with the coupled climate-chemistry model (CCM) ECHAM4.L39(DLR)/CHEM shows a stratospheric water vapor increase over the last two d...
The potential impact of ClOx radical complexes on polar stratospheric ozone loss processes
ClOx radical complexes polar stratospheric ozone
2009/1/13
The importance of radical-molecule complexes for atmospheric chemistry has been discussed in recent years. In particular, the existence of a ClO·O2 and ClOx water radical complexes like ClO·H2O, OClO·...
Characteristics and error estimation of stratospheric ozone and ozone-related species over Poker Flat (65° N, 147° W), Alaska observed by a ground-based FTIR spectrometer from 2001 to 2003
error estimation stratospheric ozone Alaska FTIR spectrometer
2008/12/15
It is important to obtain the year-to-year trend of stratospheric minor species in the context of global changes. An important example is the trend in global ozone depletion. The purpose of this paper...
Solar cycle variations of stratospheric ozone and temperature in simulations of a coupled chemistry-climate model
Solar cycle stratospheric ozone coupled chemistry-climate model
2008/12/4
The results from three 45-year simulations of a coupled chemistry climate model are analysed for solar cycle influences on ozone and temperature. The simulations include UV forcing at the top of the a...
