The intermediate ions of the atmosphere

Proceedings of the Physical Society, 1939
Evidence is produced to show that (a) the smaller nucleated ions in city air exist in separate groups with distinct mobilities; (b) the variation of the mobility of these ions with humidity is such as to lead to the conclusion that the ions are composed of droplets of sulphuric acid; (c) it appears that the ions result from the aggregation of particles

Ions in the Terrestrial Atmosphere and Other Solar System Atmospheres

Space Science Reviews, 2008
Charged molecular clusters, traditionally called small ions, carry electric currents in atmospheres. Charged airborne particles, or aerosol ions, play an important role in generation and evolution of atmospheric aerosols. Growth of ions depends on the trace gas content, which is highly variable in the time and space.

Mobility spectrometry of the atmospheric ions in relation to atmospheric pollution

pure and applied geophysics, 1972
The dynamic spectra of the atmospheric ions with mobilities between 3.2×10−4 m2/V sec and 1.3×10−8 m2/V sec were obtained in the clean and the polluted atmosphere. Based on the results, the size spectra of the submicron aerosols were deduced which show that the distribution function in Junge's expression increases in proportion to the radius of ...

Ion balance equation in the atmosphere

Journal of Geophysical Research: Atmospheres, 1997
Cosmic rays are the main source of ions in the atmosphere at altitudes of 5–35 km. The flux of cosmic rays in the atmosphere depends on the site of observation and is controlled by the geomagnetic field. Except for the rare cases of solar proton events and Forbush decreases, cosmic ray flux varies slowly with changes of solar activity level. Thus there

Atmospheric electron–ion and ion–ion recombination processes

Canadian Journal of Chemistry, 1969
The electron–ion and ion–ion recombination processes of importance in the upper atmosphere are considered, and available laboratory experimental and theoretical information concerning the relevant processes is discussed. For atomic ions the principal electron–ion recombination process is radiative, with theory indicating that the two-body coefficient ...

Interaction of Atmospheric Ions with Biological Material

Physics in Medicine and Biology, 1960
The object of this study was to investigate some of the possible physical and chemical bases for the alleged physiological effects of inhaled ionization on humans. Evidence is adduced from ` glow discharge electrolysis ' experiments to show that the ordinary ` small ions ' of atmospheric electricity carry appreciable quantities of chemical and ...

Meteoric ions in the atmosphere of Mars

Planetary and Space Science, 2003
Abstract The effect of the metallic concentration in meteoric material in the Martian ionosphere has been investigated with the scope of exploring the possible existence of meteoric ionospheric layers as it occurs on Earth. We have calculated the ion and neutral deposition of the most abundant metals in meteoroids, iron, magnesium and silicon, and ...

Atmospheric Metal Ion Chemistry

Radio Science, 1972
The role of metal ion chemistry in the atmosphere is briefly reviewed. The available relevant thermal energy binary and three‐body reaction rate data are tabulated. The importance of a two‐step hydration of metal ions is pointed out, first three‐body association of metal ions to CO2 (or possibly O2 or N2) followed by a fast binary ‘switching’ reaction,

Processes Involving Atmospheric Ions

2020
Processes of ion formation in the atmosphere and their decomposition, as well as the behavior of ions in the troposphere, are analyzed. Cosmic rays including protons and neutrons of GeV energies, as well as hard radiation of galactic or solar origin, penetrate in the atmosphere and lead to the ionization of air molecules through nuclear reactions.

Ion temperature in the upper atmosphere

Journal of Geophysical Research, 1967
The problem of ion temperature in the ionosphere is analyzed in terms of an energy budget that includes heating by the ambient electron gas, cooling by the different gases of the neutral atmosphere, and thermal conduction along the lines of geomagnetic force.
