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).

Authors:
Avallone L.Schofield R.Hertzog A.Kalnajs L.

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)
Authors:
Schofield R.Lane T.Wohltmann I.Rex M.
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.

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)…

This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…
