In the past 40 years, atmospheric chemists have come to realize that halogens exert a
powerful influence on the chemical composition of the troposphere and through that …

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 …

We use a global three‐dimensional model simulation of atmospheric methanol to examine
the consistency between observed atmospheric concentrations and current understanding …

Methanol is a biogeochemically active compound and a significant component of the volatile
organic carbon in the atmosphere. It influences background tropospheric photochemistry …

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

Hydrogen peroxide (HOOH) in ice and snow is an important chemical tracer for the oxidative
capacities of past atmospheres. However, photolysis in ice and snow will destroy HOOH and …

Laser-induced fluorescence detection was used to measure photolysis rates of anthracene
and naphthalene at the air− ice interface, and the kinetics were compared to those observed …

Measurements of acetone, methanol, acetaldehyde and a range of non-methane
hydrocarbons have been made in North Atlantic marine air at the Mace Head observatory …

There are few long-term datasets of volatile organic compounds (VOCs) in the High Arctic.
Furthermore, knowledge about their source regions remains lacking. To address this matter …

Recent measurements of reactive chemical species in snow and firn at polar sites have
served to underscore the importance of air–snow transfer processes in understanding …
