Evidence for a continuous decline in lower stratospheric ozone offsetting ozone layer recovery [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Ozone forms in the Earth's atmosphere from the photodissociation of molecular oxygen, primarily in the tropical stratosphere. It is then transported to the extratropics by the Brewer–Dobson circulation (BDC), forming a protective ozone layer around ...

Impact of a future H2-based road transportation sector on the composition and chemistry of the atmosphere – Part 2: Stratospheric ozone [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
The prospective future adoption of molecular hydrogen (H2) to power the road transportation sector could greatly improve tropospheric air quality but also raises the question of whether the adoption would have adverse effects on the stratospheric ozone ...

Forecast, observation and modelling of a deep stratospheric intrusion event over Europe [PDF]

open access: yes, 2003
A wide range of measurements was carried out in central and southeastern Europe within the framework of the EU-project STACCATO (Influence of Stratosphere-Troposphere Exchange in a Changing Climate on Atmospheric Transport and Oxidation Capacity) with ...

The Antarctic stratospheric nitrogen hole: Southern Hemisphere and Antarctic springtime total nitrogen dioxide and total ozone variability as observed by Sentinel-5p TROPOMI [PDF]

open access: yesAtmospheric Chemistry and Physics
Denitrification within the stratospheric vortex is a crucial process for Antarctic ozone hole formation, resulting in an analogous stratospheric “nitrogen hole”.

Rethinking reactive halogen budgets in the midlatitude lower stratosphere [PDF]

open access: yes, 1999
Current stratospheric models have difficulties in fully explaining the observed midlatitude ozone depletion in the lowermost stratosphere, particularly near the tropopause.

Stratospheric Ozone

open access: yes, 2021
Abstract The international effort to protect the stratospheric ozone layer successfully integrated science and technology into international environmental diplomacy and solved a global environmental problem. Research scientists identified the problem and its cause, winning a Nobel Prize for their efforts.

Causes of interannual variability over the southern hemispheric tropospheric ozone maximum [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
We examine the relative contribution of processes controlling the interannual variability (IAV) of tropospheric ozone over four sub-regions of the southern hemispheric tropospheric ozone maximum (SHTOM) over a 20-year period.

Atmospheric Abundances, Trends and Emissions of CFC-216ba, CFC-216ca and HCFC-225ca [PDF]

open access: yes, 2014
The first observations of the feedstocks, CFC-216ba (1,2-dichlorohexafluoropropane) and CFC-216ca (1,3-dichlorohexafluoropropane), as well as the CFC substitute HCFC-225ca (3,3-dichloro-1,1,1,2,2-pentafluoropropane), are reported in air samples collected

The importance of interactive chemistry for stratosphere–troposphere coupling [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Recent observational and modeling studies suggest that stratospheric ozone depletion not only influences the surface climate in the Southern Hemisphere (SH), but also impacts Northern Hemisphere (NH) spring, which implies a strong interaction between ...

Correlating tropospheric column ozone with tropopause folds: the Aura-OMI satellite data [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
The geographic and temporal variations in tropospheric and stratospheric ozone columns from individual swath measurements of the Ozone Monitoring Instrument (OMI), on the NASA Aura spacecraft, are reasonably well simulated by the University of California,
