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 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: An Industrial and Environmental Science is a comprehensive account of the science and technology of aerosols as well as their aerodynamic and physico-chemical properties. Measurement techniques and results are presented in terms of a framework of classical mechanics and macroscopic chemistry. This book is comprised of 10 chapters and begins with a discussion on the foundations of modern aerosol science and technology, followed by a review of the dynamic theory of aerosols as rigid spheres. The production of particle suspensions, the methods of particle sampling and measurement, and physical or chemical characterization are then considered, along with particle diffusion by Brownian motion, particle formation and growth, and coagulation processes. The formation of particle clouds is described by means of molecular agglomeration (condensation) processes, breakup and disintegration, and chemical reactions. The remaining chapters focus on several major applications of aerosol science in areas such as combustion, agriculture, and medicine. This monograph is intended to serve scientists and engineers who are concerned with the underlying principles of aerodynamic and physical chemical behavior of aerosols, and could also be used as a text for graduate students in specialized courses on aerosol or colloid chemistry, atmospheric processes, and chemical, mechanical, or environmental engineering.

Gives a short and coherent presentation of the chemical composition of aerosol particles contributing to detrimental atmospheric and environmental conditions. After review of physical properties and measuring procedures, the formation of aerosol particles in the atmosphere determining aerosol composition is summarized. Present knowledge of particle composition is discussed, and the impact of aerosol particles on cloud formation, visibility degradation, climate variations, and ozone depletion is described.
