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 plays an important role in providing atmospherically derived semi-volatile organic
compounds (SVOCs) to regions of high latitude and altitude. The accumulated winter …

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 physical, chemical, and biological processes involving organics in ice in the
environment impact a number of atmospheric and biogeochemical cycles. Organic material …

Snow is a very active photochemical reactor that considerably affects the composition and
chemistry of the lower troposphere in polar regions. Snow photochemistry models have …

Sorption from air to one snow sample has been measured for a broad set of organic vapors
covering a wide range of physicochemical properties. Those results that could be compared …

Acetaldehyde (CH3CHO) and acetone (CH3C (O) CH3) concentrations in ambient air, in
snowpack air, and bulk snow were determined at Alert, Nunavut, Canada, as a part of the …

Snowpacks contain many carbonaceous species that can potentially impact on snow albedo
and arctic atmospheric chemistry. During the OASIS field campaign, in March and April …

Experiments were conducted during the ALERT 2000 field campaign aimed at
understanding the role of air–snow interactions in carbonyl compound chemistry and the …

The specific surface area (SSA) of snow determines in part the albedo of snow surfaces and
the capacity of the snow to adsorb chemical species and catalyze reactions. Despite these …
