Climatology and trends in the forcing of the stratospheric ozone transport [PDF]

Atmospheric Chemistry and Physics, 2011
A thorough analysis of the ozone transport was carried out using the Transformed-Mean Eulerian (TEM) tracer continuity equation and the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40). In this budget analysis, the chemical

Projecting ozone hole recovery using an ensemble of chemistry–climate models weighted by model performance and independence

Atmospheric Chemistry and Physics, 2020
. Calculating a multi-model mean, a commonly used method for ensemble averaging, assumes model independence and equal model skill. Sharing of model components amongst families of models and research centres, conflated by growing ensemble size, means ...

On the use of satellite observations to fill gaps in the Halley station total ozone record [PDF]

Atmospheric Chemistry and Physics, 2021
Measurements by the Dobson ozone spectrophotometer at the British Antarctic Survey's (BAS) Halley research station form a record of Antarctic total column ozone that dates back to 1956.

Transport and mixing processes during the Antarctic ozone increase

Antarctic Record, 2010
The 44th Japanese Antarctic Research Expedition (JARE-44) performed intensive ozonesonde observations at Syowa Station (69.0゜S, 39.6゜E) from June 2003 through January 2004 to clarify the time evolution and mechanism of the Antarctic ozone hole ...

Signs of Slowing Recovery of Antarctic Ozone Hole in Recent Late Winter–Early Spring Seasons (2020–2023)

Atmosphere
Every year since the early 1980s, the ozone hole has appeared in late winter/spring over Antarctica. The ozone hole is expected to disappear due to the observed decrease in the concentration of ozone-depleting substances in the stratosphere, which is ...

The evolution of zonally asymmetric austral ozone in a chemistry–climate model [PDF]

Atmospheric Chemistry and Physics, 2017
Asymmetry in the Southern Hemisphere stratospheric ozone hole is important due to both direct radiative heating and its effect on dynamics. It is also a strong indicator of the underlying quality of the stratospheric dynamics of a climate model.

Does Cosmic-Ray-Induced Heterogeneous Chemistry Influence Stratospheric Polar Ozone Loss ? [PDF]

, 2009
Cosmic-ray (CR) -induced heterogeneous reactions of halogenated species have been suggested to play the dominant role in causing the Antarctic ozone hole.

Heterogeneous PSC ozone loss during an ozone mini‐hole [PDF]

Geophysical Research Letters, 1997
An upper tropospheric high pressure system resulting in large scale ascent even in the stratosphere, is investigated by means of simulations using the coupled dynamic‐chemical general circulation model ECHAM3/CHEM. These simulations show two kinds of impact on stratospheric ozone.

Demonstration of a physical inversion scheme for all-sky, day-night IASI observations and application to the analysis of the onset of the Antarctica ozone hole: assessment of retrievals and consistency of forward modeling

Journal of Quantitative Spectroscopy and Radiative Transfer
Based on a recently developed all-sky forward model ( σ -IASI/F2N) for the computation of spectral radiances in the range 100 to 2760 cm -1 , the paper addresses the spring onset of the Antarctica ozone hole with infrared observations from the IASI ...
