Abstract. Observations of the unique chemical environment over snow
and ice in recent decades, particularly in the polar regions, have
stimulated increasing interest in the boundary layer processes that mediate
exchanges between the ice/snow interface and the atmosphere. This paper
provides a review of the underlying concepts and examples from recent field
studies in polar boundary layer meteorology, which will generally apply to
atmospheric flow over snow and ice surfaces. It forms a companion paper to
the chemistry review papers in this special issue of ACP that focus on
processes linking halogens to the depletion of boundary layer ozone in
coastal environments, mercury transport and deposition, snow photochemistry,
and related snow physics. In this context, observational approaches, stable
boundary layer behavior, the effects of a weak or absent diurnal cycle, and
transport and mixing over the heterogeneous surfaces characteristic of
coastal ocean environments are of particular relevance.
