The parties to the Montreal Protocol are informed by three panels of experts. One of these is the … Environmental Effects Assessment Panel (EEAP), which deals with two focal issues. The first focus is … the effects of increased UV radiation on human health, animals, plants, biogeochemistry…
To better attribute the total ozone column (TOC) anomalies observed from the ozone … measurements in Ukraine, the climatologies of annual ozone cycle along the latitudinal … band 40–60° N with the 30° step in longitude have been analysed.
Although huddling was shown to be the key by which emperor penguins (Aptenodytes forsteri) save energy and sustain their breeding fast … during the Antarctic winter, the intricacies of this social behavior have been poorly studied.
Preliminary findings from the Australian contribution to the Chemistry-Climate Model Initiative (CCMI) are presented. This initiative builds on the 2nd Chemistry Climate Modelling Validation (CCMVal-2), Atmospheric Chemistry & Climate (AC&C) and other global modelling.
This study aims to assess the ability of climate models to reproduce observed stratosphere-troposphere coupling. Coupling between the stratosphere and troposphere is examined via the Southern and Northern Annular Modes (SAM and NAM). These modes…
Trends in surface atmospheric variables, namely temperature, wind speed and direction, cloud cover, and precipitation, display subtle patterns that are likely linked to climate change and the major modes of climate variability. In particular…
The continent of Antarctica has experienced some of the largest rates of both surface warming and cooling found anywhere on the planet. Unlike in the Arctic, where sea ice has been declining…
The Southern Ocean islands are some of the most isolated landmasses in the world. Few of the islands support permanent human settlements or land based industries and as such they remain as some of the most uninvaded landscapes globally.
A Rayleigh lidar at Davis, Antarctica (69S, 78E) has made intermittent observations of clouds for the last few years. Radiosondes and a co-located wind-profiling radar provide additional data with which to characterise the clouds and the environment in which they exist.
Polar Stratospheric Cloud (PSC) composition class information is extracted from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) curtains for four Antarctic PSC seasons (2007 - 2010) and four Arctic PSC seasons (2006/07 - 2009/10). Orographic gravity wave (OGW)…
