Weather and climate models are challenged by uncertainties and biases in simulating
Southern Ocean (SO) radiative fluxes that trace to a poor understanding of cloud, aerosol …

Atmospheric deposition of mercury onto sea ice and circumpolar sea water provides
mercury for microbial methylation, and contributes to the bioaccumulation of the potent …

Stratocumulus clouds over the Southern Ocean have fewer droplets and are more likely to
exist in the predominately supercooled phase than clouds at similar temperatures over …

The Southern Ocean (SO) and Antarctica play important roles in the global climate. The new
particle formation (NPF) alters the availability of cloud condensation nuclei (CCN), leading to …

Overview of the Antarctic Circumnavigation Expedition: Study of Preindustrial-like Aerosols
and Their Climate Effects (ACE-SPACE) in: Bulletin of the American Meteorological Society …

Long-range transport of biogenic emissions from the coast of Antarctica, precipitation
scavenging, and cloud processing are the main processes that influence the observed …

Abstract The Southern Ocean region is one of the most pristine in the world and serves as
an important proxy for the pre-industrial atmosphere. Improving our understanding of the …

Abstract During summer, the Southern Ocean is largely unaffected by anthropogenic
emissions, which makes this region an ideal place to investigate marine natural aerosol …

The atmosphere is the primary medium for long-distance transport and transformation of
elemental mercury (Hg), a potent neurotoxin. The recent discovery of mass-independent …

This commentary paper from the recently formed International Global Atmospheric
