Examines the hygroscopic and morphological nature of various substances through the use of an Environmental Scanning Electron Microscope (ESEM). The hygroscopic growth and changes in morphology for pure-component aerosols were studied for particles size. Hygroscopic growth was observed through changes in relative humidity (RH) and hygroscopic growth curves were created. the hygroscopic growth of multi-component aerosol mixtures was studied using Hygroscopic Tandem Differential Mobility Analysis (HTDMA) . The size distribution for an aerosol stream was determined before and after the stream was subjected to an increase in relative humidity.

Aerosols play vital roles in energy balance of the Earth and also have a significant impact on human health. The last assessment report by the Intergovernmental Panel on Climate Change (IPCC), states that the uncertainty in the total radiative forcing is mainly dominated by the high uncertainty in the aerosol radiative forcing. This is mainly caused by the poorly understood and quantified aerosol effects. Indeed, high relative humidity (RH), promotes water uptake by atmospheric aerosol particles, which modifies their size, morphology and chemical composition and therefore their optical properties. In-situ measurements of aerosols properties (scattering and absorption coefficients, size distribution) are usually performed at dry conditions (RH

This book provides the first comprehensive analysis of how aerosols form in the atmosphere through in situ processes as well as via transport from the surface (dust storms, seas spray, biogenic emissions, forest fires etc.). Such an analysis has been followed by the consideration of both observation data (various field observational experiments) and numerical modeling results to assess climate impacts of aerosols bearing in mind that these impacts are the most significant uncertainty in studying natural and anthropogenic causes of climate change.

Examines the hygroscopic properties of increasingly complex, and thus increasingly realistic, aerosols. This was accomplished in three different experimental investigations. Initially, single-component aerosols were examined. Then, multi-component organic aerosols were characterized. Finally, ambient aerosols were collected in the field and analyzed.

The uncertainties in the aerosol effects on radiative forcing limit our knowledge of climate change, presenting us with an important research challenge. Aerosols in Atmospheric Chemistry introduces basic concepts about the characterization, formation, and impacts of ambient aerosol particles as an introduction to graduate students new to the field. Each chapter also provides an up-to-date synopsis of the latest knowledge of aerosol particles in atmospheric chemistry.

Atmospheric aerosols are an important and a highly complex component of the Earth’s atmosphere that alter the radiative forcing and the chemical composition of the gas phase. These effects have impacts on local air quality and the global climate. Atmospheric Aerosol Chemistry outlines research findings to date in aerosol chemistry and advances in analytical tools used in laboratory settings for studying their surface and bulk reactivity.
