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…
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).
The parameterization of gravity waves in the NCAR Whole Atmosphere Community Climate Model (WACCM) includes orographic, convective, and frontal sources. Even with these, the model simulates temperatures in the Antarctic lower stratosphere during winter and spring that are much lower than observed.
We compare the merits of potential observatory sites on the … Antarctic Plateau, in regard to the boundary layer, cloud cover, free … atmosphere seeing, aurorae, airglow, and precipitable water vapour. We find that (a)…
The Antarctic plateau contains the best sites on earth for many forms of astronomy, but … none of the existing bases was selected with astronomy as the primary motivation. In this paper, we try to systematically compare the merits of potential observatory sites. We include South … Pole, Domes A…
Macquarie Island, a small subantarctic island, is home to rockhopper, royal and king penguins, which are often infested with the globally distributed seabird tick, Ixodes uriae. A flavivirus, an orbivirus, a phlebovirus, and a nairovirus were isolated from these ticks and partial sequences obtained.
We used a Rayleigh lidar located at Davis station, East Antarctica, to compare Polar … Mesospheric Cloud (PMC) and stratospheric gravity wave (GW) strengths in the … austral summer 2005–2006.
[1] Using Rayleigh lidar and Mesosphere-Stratosphere- … Troposphere radar at Davis Antarctica (68.6S) during the … 2005–2006 austral summer, we obtained the first Southern … Hemisphere common-volume measurements of Polar … Mesospheric Clouds (PMC) and Polar Mesosphere … Summer Echoes (PMSE).
We compiled and reviewed 248 cases of reported vessel collisions with small cetaceans worldwide and with large … cetaceans in the Southern Hemisphere. Difficulties were encountered with the comparison of highly variable data in … terms of quality (evidence), sources…
The operating principle of atmospheric Rayleigh LIDAR (light … detection and ranging) systems is that the range-corrected return backscatter … signal is directly related to atmospheric density.
