Abstract
Introduction
In recent years, there has been a great deal of interest in the heterogeneous chemistry of trace atmospheric gases on aqueous and solid-phase particles present in the troposphere. An understanding of these reactions is critical as they affect a multitude of atmospheric processes. For example, particulates can alter the chemical balance of the atmosphere by providing a reactive substrate or medium on and in which reactions can occur. The thermodynamic and optical properties of atmospheric particles may also be altered as their chemical composition changes during these reactions. In turn, climate forcing by atmospheric particles through absorption and scattering of solar radiation will depend on its chemical history. Climate forcing by particulates is currently recognized as one of the greatest uncertainties in global climate models. Although there are a variety of particulates present in the atmosphere, this review will focus on mineral dust and its role in altering atmospheric processes. To better understand the heterogeneous reactions that can occur, some aspects of the physical and chemical properties of mineral dust, known transport processes, environmental implications, and the first atmospheric chemistry models that included heterogeneous reactions are summarized in this introductory section.
