We examine recently collected cloud observations made from the surface of the Southern Ocean using W-band cloud radar, ceilometer and a polarization capable lidar. The data were collected as part of several ship- and Macquarie Island-based campaigns between 2016 and 2018.
Persistent organic pollutants (POPs) are well known to accumulate in polar food webs; yet there is little ecotoxicological data available for environmental risk assessment of POPs in these extreme ecosystems. The premise of the tissue residue approach (TRA)…
A Raman depolarization lidar was deployed at Cape Grim, Australia (40.7°S, 144.7°E), at the northern edge of the Southern Ocean from July 2013 to February 2014 from which we determine cloud boundaries, cloud phase, ice virga, and cloud effective top heights.
The Southern Hemisphere … Antarctic stratosphere experienced two noteworthy events in 2015: a … significant injection of sulfur from the Calbuco volcanic eruption in Chile … in April, and a record-large Antarctic ozone hole in October and November. Here…
Near-synchronized in situ, space-borne (A-Train) and ground-based … lidar observations are employed to evaluate the boundary-layer clouds (BLCs) over Tasmania and the adjacent Southern Ocean (SO) simulated by the … limited-area version of Australian Community Climate and Earth System … Simulator…
We present an overview of … state-of-the-art chemistry–climate and chemistry transport models that … are … used within phase 1 of the Chemistry–Climate Model Initiative (CCMI-1).
Radiative forcing resulting from stratospheric aerosols produced by major volcanic eruptions is a dominant driver of climate variability in the Earth's past.
Human activities in Antarctica pose significant threats to marine ecosystems through accidental fuel spills, primarily as aresult of shipping incidents. This risk is likely to increase due to rises in shipping frequency in the Southern Ocean.
Better characterisation of aerosol processes in pristine, natural environments, such as Antarctica, have recently been shown to lead to the largest reduction in uncertainties in our understanding of radiative forcing.
Chemistry–climate models are important tools for addressing interactions of composition and climate in the Earth system. In particular, they are used to assess the combined roles of greenhouse gases and ozone in Southern Hemisphere climate and weather.
Future changes in the boreal polar vortex under a climate change scenario are still a matter of debate in the scientific community. For example, there is a lack of consensus among models about possible future changes in the frequency of major stratospheric warmings.
The oxygen and deuterium isotopic composition of ice represent a prodigal source of information for the reconstruction of past climate.
