Ecosystems and the atmosphere: This review describes the state of understanding the
processes involved in the exchange of trace gases and aerosols between the earth's surface …

Dry deposition can account for a large portion of the removal of trace chemicals from the
troposphere. Resistance schemes used in modeling often perform quite well in daytime …

Particle pH is a critical but poorly constrained quantity that affects many aerosol processes
and properties, including aerosol composition, concentrations, and toxicity. We assess PM1 …

The chemical processing of pollutants emitted into the atmosphere leads to a variety of
oxidised products, which are commonly referred to as secondary pollutants. Such pollutants …

The relationship between O3 and NOx (NO+ NO2) which was measured during summer and
winter periods at Niwot Ridge, Colorado, has been analyzed and compared to model …

Because there is no simple device capable of measuring the dry deposition rates of small
particles and trace gases directly, much current activity is focused on the use of an inferential …

Research on air pollution and acidic deposition during the last 15 yr has greatly increased
our knowledge of the rates and the processes of atmospheric deposition. The invigoration of …

Knowledge of atmospheric mercury speciation is critical to understanding its fate once
released from point sources. The water-soluble compounds of Hg that exist in flue gases …

pH is a fundamental aerosol property that affects ambient particle concentration and
composition, linking pH to all aerosol environmental impacts. Here, PM 1 and PM 2. 5 pH …

Carbon and Nitrogen in the Terrestrial Environment is a comprehensive, interdisciplinary
description of C and N fluxes between the atmosphere and the terrestrial biosphere; issues …
