It has been shown that sunlit snow and ice plays an important role in processing
atmospheric species. Photochemical production of a variety of chemicals has recently been …

Snow in the environment acts as a host to rich chemistry and provides a matrix for physical
exchange of contaminants within the ecosystem. The goal of this review is to summarise the …

Two consecutive cruises in the Weddell Sea, Antarctica, in winter 2013 provided the first
direct observations of sea salt aerosol (SSA) production from blowing snow above sea ice …

Stratigraphic boundaries are ideally defined by distinct lithological, geochemical, and
palaeobiological signatures, to which a chronological framework can be applied. We …

A one-dimensional chemical transport model has been developed to investigate the vertical
gradients of bromine and iodine compounds in the Antarctic coastal boundary layer (BL) …

28 February 2017 marked 75 years since the first confident registration of solar cosmic rays
(SCRs), ie, accelerated solar particles with energies from about 10 6 to~ 10 10÷ 10 11 eV …

Atmospheric samples and snowfall collected in coastal East Antarctica over two years are
used to investigate the sources, production of atmospheric nitrate (NO 3−) and its link with …

To gain a better understanding of sulfate and methanesulfonate (MS−) signals recorded in
central Antarctic ice cores in terms of past atmospheric changes, an atmospheric year‐round …

Current chemistry climate models do not include polar emissions and chemistry of halogens.
This work presents the first implementation of an interactive polar module into the very short …

Nitrate is frequently measured in ice cores, but its interpretation remains immature. Using
daily snow surface concentrations of nitrate at Halley (Antarctica) for 2004–2005, we show …
