Atmospheric Electricity and Aerosol-Cloud Interactions in Earth's Atmosphere

Firstly, atmospheric ions play an important role in the fair weather electricity in Earth's atmosphere. Small ions, or charged molecular clusters, carry electric currents in the atmosphere. These small ions are continuously present, and their …

Does the Onset of New Particle Formation Occur in the Planetary Boundary Layer?

The planetary boundary layer (PBL) is chemically and physically the most active and complex part of the atmosphere as it has high loading of both aerosols and gaseous precursors. To detect directly the first steps of new particle formation in the …

Self-consistent binary cluster-size distributions of sulfuric acid-water system

The new self-consistent and partially self-consistent forms of binary distribution function are proposed. The activities (number concentrations) of sulfuric acid and water calculated by these distributions at unit nucleation rate are compared between …

Derivation of the size spectrum of aerosol particles from a mobility spectrum

The mobility spectra of air ions measured in atmospheric electrical research give essential information about atmospheric aerosols. The air ions and aerosol particles were simultaneously measured during a monthly period at a rural site and the …

Nucleation in the presence of air ions and aerosol particles

It is shown that the replacement of difference equations of cluster size distribution, in the standard way in classical nucleation theory, by differential equation gives erroneous cluster size distribution in the case of cluster scavenging by an …
