The physical state of a material is described as its phase. Common phases of the molecule
H2O include vapor, liquid water, and ice. Examples of these phases in the atmosphere are …

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 …

A workshop was held in the framework of the ACCENT (Atmospheric Composition Change–
a European Network) Joint Research Programme on" Aerosols" and the Programme on" …

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 …

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

Considerable interest in the interactions of trace gases with ice surfaces has only developed
of late, in large part prompted by the discovery of the Antarctic Ozone Hole and the …

Ice templating–or freeze casting–has flourished in multiple domains as a straightforward
process to shape solutions and particle suspensions into macroporous materials. Longtime …

Nitrate photolysis proceeds via two major channels at illumination wavelengths above 290
nm: NO3-+ h ν (+ H+)→ NO2+• OH (1) and NO3-+ h ν→ NO2-+ O (3P)(2). A recent study …

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

To help quantify exchanges between the atmosphere and the snow cover, we have
measured the specific surface area (SSA) of 176 snow samples taken from the seasonal …
