The 2013 Antarctic ozone hole. Atmospheric Composition and Chemistry Observations and Modelling Conference incorporating the Cape Grim Annual Science Meeting, Aspendale, Victoria, Australia 27-29 November 2013, 2013 (Ref: 15135)
Category 3: Conference paper

The 2013 ozone hole was relatively small, with about 15-17 ozone holes out of the last 20 (1994-2013) having been bigger/deeper (depending on the metric used), and only 2-4 having been smaller (2002, 2004, 2010, 2012).

Atmospheric chemistry measurements over the East Antarctic during the SIPEX II cruise in polar spring 2012. Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15128)
Category 3: Verbal presentation

Bromine explosion events that occur over first year sea ice in the polar spring cause mercury deposition and dramatically alter the oxidative capacity of the polar boundary layer. Atmospheric chemical measurements made during the Sea Ice Physics and Ecosystems eXperiment (SIPEX II)…

Calculations of Ozone Loss Rates within the Antarctic “Ozone Hole” using Quasi-Lagrangian Measurements of Ozone made during the Concordiasi Long-duration Balloon Campaign. Quadrennial Ozone Symposium 2012, Toronto, Canada, 27-31 August, 2012 (Ref: 15105)
Category 3: Verbal presentation

Considerable progress in our understanding of the causes of polar stratospheric ozone loss has been made during the past two decades. However, model calculations are still limited by uncertainties in both chemical and dynamical factors.

Tropical tropopause layer processes driving stratospheric composition - focus on polar ozone relevant species. XXXII SCAR and Open Science Conference, Portland, Oregon, USA, 13-25 July 2012, 2013 (Ref: 15104)
Category 3: Verbal presentation

The composition of the stratosphere is driven by transport, temperatures and processes in the tropical tropopause layer – this has implications for ozone, radiation, and surface climate. The properties of the tropical tropopause layer have changed in recent decades, e.g.

Backward movement of ozone minimum position as a possible consequence of ozone recovery over Antarctica. American Geophysical Union 2013 Fall Meeting, San Francisco USA, 9-12 December 2013, 2013 (Ref: 15136)
Category 3: Poster

The ozone hole over Antarctica is formed inside polar stratospheric vortex, which is under influence of large-scale planetary waves. The Quasi-stationary wave (QSW) in the spring Southern Hemisphere (SH)…

The Australian Contribution to CCMI Part II: Model evaluation using Southern Hemispheric ozone observations. Chemistry-Climate Model Initiative Workshop 2013, Boulder, Colorado, USA, 14-16 May 2013, 2013 (Ref: 15134)
Category 3: Poster

Results from the chemistry—atmosphere—climate model version of the Australian Community Climate and Earth System Simulator (ACCESS) are presented. ACCESS is based on the UK Met Office Unified Model version 7.3 (UM 7.3) including the United Kingdom Chemistry and Aerosols (UKCA) module.

Influences of circulation changes on the distribution of Antarctic stratospheric ozone. Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15132)
Category 3: Poster

The cause of seasonal trends in the zonal asymmetry of the total ozone column (TOC) at high southern latitudes are examined. Using ERA-Interim assimilated meteorological data, we examine characteristics of extra-tropical Rossby waves…

Improving gravity wave drag parameterization in climate models. Davos Atmosphere and Cryosphere Assembly 2013, Davos, Switzerland, 8-12 July 2013, 2013 (Ref: 15131)
Category 3: Poster

Links between changes in the southern polar stratosphere and tropospheric climate have been identified in both modelling and observational studies, highlighting the importance of an accurate stratosphere in climate models. However…

High-resolution Antarctic observations of the stratospheric influence on the troposphere. 3rd International Conference on Earth System Modelling, Hamburg, Germany, 17-21 September 2012, 2012 (Ref: 15127)
Category 3: Poster

The upper troposphere and lower stratosphere (UTLS) is a highly coupled region of the atmosphere where radiation, dynamics, clouds and chemical processes interact on a wide variety of spatial and temporal scales. We use a suite of instruments at Davis, Antarctica (69S, 78E)…

Southern polar stratospheric metrics of the Australian Community Climate and Earth System Simulator (ACCESS). 3rd International Conference on Earth System Modelling, Hamburg, Germany, 17-21 September 2012, 2012 (Ref: 15126)
Category 3: Poster

We use a set of metrics for the polar atmosphere to compare coupled ocean-atmosphere general circulation models (AOGCMs) experiments for the 5th Coupled Model Intercomparison Project (CMIP5) with results from chemistryclimate models (CCMs) of the 2nd Chemistry-Climate Model Validation (CCMVal-2)…

Ozone loss rates from Concordiasi Balloon experiment comparison with recommended kinetics. World Climate Research Programme (WCRP) Special Workshop: Climatic Effects of Ozone Depletion in the Southern Hemisphere, Buenos Aires, Argentina, 25 February - 1 March 2013, 2013 (Ref: 15103)
Category 3: Poster

The ozone loss simulated with climate models is based on laboratory kinetic data. These laboratory data are difficult to conduct at stratospheric pressures and temperatures and there is substantial uncertainty surrounding these parameters.
