Dry deposition of ozone is an important sink of ozone in near‐surface air. When dry
deposition occurs through plant stomata, ozone can injure the plant, altering water and …

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 …

The presence of snow greatly perturbs the composition of near-surface polar air, and the
higher concentrations of hydroxyl radicals (OH) observed result in a greater oxidative …

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

The image of Antarctica as a symbol of the last great wilderness and pristine environment
has changed considerably in the last two decades. Environmental problems such as the …

The cryosphere is an important component of global organic contaminant cycles. Snow is an
efficient scavenger of atmospheric organic pollutants while a seasonal snowpack, sea ice …

This paper addresses the potential role of surface wetness in ozone deposition to plant
foliage. We studied Scots pine foliage in field conditions at the SMEARII field measurement …

An unknown fraction of mercury that is deposited onto the cryosphere is emitted back to the
atmosphere. Since mercury that enters the meltwater may be converted to highly toxic …

We report first direct measurements of the partial pressure of CO2 (pCO2) within Antarctic
pack sea ice brines and related CO2 fluxes across the air‐ice interface. From late winter to …

Gaseous elemental mercury (GEM) concentration measurements were made during the
Alert 2000 campaign in Alert, Nunavut, Canada, between February and May 2000. GEM …
