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 …

Nitrous acid (HONO) plays a key role in tropospheric photochemistry, primarily due to its role
as a source of hydroxyl (OH) radicals via its rapid photolysis. OH radicals are involved in …

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 …

Nitrous acid (HONO) is an important precursor of the hydroxyl radical (OH), the self‐cleaning
agent of the atmosphere and a key species in the formation of harmful photooxidants during …

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

Atmospheric nitrogen oxides (NOx= NO+ NO2) play a pivotal role in the cycling of reactive
nitrogen (ultimately deposited as nitrate) and the oxidative capacity of the atmosphere …

Snow, through its trace constituents, can have a major impact on lower tropospheric
chemistry, as evidenced by ozone depletion events (ODEs) in oceanic polar areas. These …

The protonation degree of cresol red (CR) in frozen aqueous solutions at 253 or 77 K,
containing various acids (HF, HCl, HNO3, H2SO4, and p-toluenesulfonic acid), sodium …

Over the past two decades, with recognition that the ocean's sea-ice cover is neither
insensitive to climate change nor a barrier to light and matter, research in sea-ice …

Photochemical reactions of trace compounds in snow have important implications for the
composition of the atmospheric boundary layer in snow-covered regions and for the …
