Atmospheric particles are ubiquitous in the atmosphere: they form the seeds for cloud droplets and they form haze layers, blocking out incoming radiation and contributing to a partial cooling of our climate. They also contribute to poor air quality and health impacts. A large fraction of aerosols are formed from nucleation processes a that is a phase transition from vapour to liquid or solid particles. Examples are the formation of stable clusters about 1 nm in size from molecular collisions and these in turn can grow into larger (100 nm or more) haze particles via condensation to the formation of ice crystals in mixed phase or cold clouds. This book brings together the leading experts from the nucleation and atmospheric aerosols research communities to present the current state-of-the-art knowledge in these related fields. Topics covered are: Nucleation Experiment a Theory, Binary, Homogeneous and Heterogeneous Nucleation, Ion a Cluster Properties During Nucleation, Aerosol Characterisation a Properties, Aerosol Formation, Dynamics and Growth, Marine Aerosol Production, Aerosol-Cloud Interactions, Chemical Composition a Cloud Drop Activation, Remote Sensing of aerosol a clouds and Air Quality-Climate InteractionsThe initial research was undertaken with two manual Nolan-Pollak (NP) condensation nucleus counters (CNC) which were used to measure the concentration and mean size of nuclei in various air masses and the fraction of them that are charged. ... to 3.0 I¼m) measurements using an optical particle counter have been carried out at Mace Head since 1987.6 More recently, use is being made of differentialanbsp;...
