Temporal and Spatial Patterns of the Interannual Variability of Stratospheric Ozone and Dynamics [PDF]

, 2004
This dissertation is a collection of empirical and modeling studies focusing on the interannual variability (IAV) of stratospheric ozone and the dynamics associated with that variability. Empirical analyses of the IAV of total column ozone in the tropics

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

Atmospheric 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 ...

Analyzing ozone variations and uncertainties at high latitudes during sudden stratospheric warming events using MERRA-2 [PDF]

Atmospheric Chemistry and Physics, 2022
Stratospheric circulation is a critical part of the Arctic ozone cycle. Sudden stratospheric warming events (SSWs) manifest the strongest alteration of stratospheric dynamics.

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

Atmospheric 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 ...

High resolution simulation of recent Arctic and Antarctic stratospheric chemical ozone loss compared to observations [PDF]

, 2005
Simulations of polar ozone losses were performed using the three-dimensional high-resolution (1° × 1°) chemical transport model MIMOSA-CHIM. Three Arctic winters 1999–2000, 2001–2002, 2002–2003 and three Antarctic winters 2001, 2002, and 2003 were ...

Long-term changes in the upper stratospheric ozone at Syowa, Antarctica [PDF]

Atmospheric Chemistry and Physics, 2014
Analyses of stratospheric ozone data determined from Dobson–Umkehr measurements since 1977 at the Syowa (69.0° S, 39.6° E), Antarctica, station show a significant decrease in ozone at altitudes higher than that of the 4 hPa pressure level during the ...

Impacts of stratospheric sulfate geoengineering on tropospheric ozone [PDF]

Atmospheric Chemistry and Physics, 2017
A range of solar radiation management (SRM) techniques has been proposed to counter anthropogenic climate change. Here, we examine the potential effects of stratospheric sulfate aerosols and solar insolation reduction on tropospheric ozone and ozone ...

Northern winter stratospheric temperature and ozone responses to ENSO inferred from an ensemble of Chemistry Climate Models [PDF]

, 2009
The connection between the El Ni˜no Southern Oscillation (ENSO) and the Northern polar stratosphere has been established from observations and atmospheric modeling. Here a systematic inter-comparison of the sensitivity of the modeled stratosphere to ENSO
