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 …

The Arctic warms nearly four times faster than the global average, and aerosols play an
increasingly important role in Arctic climate change. In the Arctic, sea salt is a major aerosol …

During springtime in the polar regions, unique photochemistry converts inert halide salt ions
(eg Br−) into reactive halogen species (eg Br atoms and BrO) that deplete ozone in the …

Following the springtime polar sunrise, ozone concentrations in the lower troposphere
episodically decline to near-zero levels. These ozone depletion events are initiated by an …

The role of ice in the formation of chemically active halogens in the environment requires a
full understanding because of its role in atmospheric chemistry, including controlling the …

Snow on the ground is a complex multiphase photochemical reactor that dramatically
modifies the chemical composition of the overlying atmosphere. A quantitative description of …

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 …

Snow lying on sea ice could be a potentially important source of sea salt aerosol, as small
snow particles, rich in salts, can be easily lifted into the air though blowing‐snow events …

Sea salt aerosols (SSA) are generated via air bubbles bursting at the ocean surface as well
as by wind mobilization of saline snow and frost flowers over sea-ice-covered areas. The …
