    Relation of the atmospheric potential gradient with meteorological elements-cross power spectral analysis (1971)
    Springer
    Pure and applied geophysics 88 (1971), S. 210-227 
    Details

    Topics: Geosciences , Physics
    Notes: Summary Simultaneous measurements of the atmospheric electric potential gradient, relative humidity, temperature, pressure and wind speed were made for seven months and the diurnal variations, power spectra, coherence spectra, cross-spectral phase spectra, contribution to variance and the time of maximum of diurnal, semi-diurnal, terdiurnal and quartodiurnal components were calculated. The rate of decrease of relative humidity together with the rate of increase of temperature appeared to influence the potential gradient. The terdiurnal component of the potential gradient was much larger than the semi-diurnal component during summer and seemed to be governed by the terdiurnal component of the rate of change of relative humidity and temperature.

    Notes: [Auszug] Barometric pressure records from both stations were sampled every 2 h throughout 1965. The year was divided into nine periods, eight of 40 days and the last one of 45 days. The analysis first estimates the autocovariance and then takes its Fourier transform to calculate the spectral density or ...

    Notes: [Auszug] At Socorro, the pressure disturbance was recorded with two hot-wire pressure transducers and also with three seismographs. The seismographs were not compensated for pressure changes and thus were not of much interest to this report. At the Mountain Laboratory, the pressure wave was recorded with a ...

    Description / Table of Contents: Zusammenfassung Es wurden die Änderungen des elektrischen Potentialgradienten an mehreren Landstationen untersucht. Die Tagesgänge zeigen nach Weltzeit und nach Ortszeit Unterschiede von Station zu Station. An einer Station sind die Tagesgänge an Schönwettertagen den als Durchschnitt aller Tage berechneten Tagesgängen ähnlich. Es wurden auch jahreszeitliche Änderungen und Potenzspektren berechnet. Harmonische Analysen ergeben den prozentuellen Beitrag zur Varianz und die Eintrittszeiten der Maxima der 24-, 12-, 8- und 6stündigen Schwingungen. Für mehr als 150 Stationspaare wurden Korrelationskoeffizienten für die stündlichen und monatlichen Mittelwerte berechnet; im allgemeinen ergeben sich dabei nur kleine Korrelationskoeffizienten.
    Notes: Summary Electric potential gradient variation at several land stations is studied. Diurnal curves in GMT and local standard time are different from station to station. For a station, fair weather diurnal curves are similar to all weather curves. Seasonal variations are calculated and power spectra are computed. Harmonic analysis is used to compute the percentage contribution to variance and the time of maximum of 24, 12, 8 and 6 hr. oscillations. Correlation coefficients of the hourly and monthly means are calculated for over one hundred and fifty station pairs. In general, low correlation coefficients are found.

    Air ion effect on respiration and photosynthesis of barley andAntirrhinum majus (1985)

    Notes: Abstract Stem height increases of 13% and 15% for barley and snapdragon respectively were observed for plants maintained in an atmosphere of high concentrations of negative air ions compared to control plants. Dry weights of the exposed plant species to negative ions increased by approximately 18% compared to untreated plants. The effects of positive air ions were insignificant. The rates of photosynthesis and respiration measurements on continuously exposed plants to negative air ions conformed to these observations.

    Enhancement of evaporation rates from thin layers of liquids exposed to air ions (1988)

    Notes: Abstract A beta-ray gauge system was used to study evaporation rates and drying times of liquids exposed to relatively high fluxes of air ions of either polarity produced by a corona discharge. Evaporation rates from thin layers of water, ethyl alcohol, and carbon tetrachloride increased considerably when exposed to air ions, compared to untreated liquids under constant environmental conditions. Drying times of liquid layers exposed to air ions were shortened by a factor of at least two over liquids that had not been exposed to ions. The drying time of a liquid layer was found to increase with the decrease of ion fluxes at the liquid surface. Threshold values of 1.9×1011 positive ions and 2.7×1011 negative ions cm−2 s−1 were established below which no increase in the evaporation rates were observed for ethyl alcohol and carbon tetrachloride. The evaporation rate of water at these same ion fluxes was significantly higher than that of the control. The present experiments indicate that a stream of air ions could play a major role in the observed enhancement of evaporation rates.

    Effects of atmospheric small negative ions on the oxygen consumption of mouse liver cells (1978)
    Springer
    International journal of biometeorology 22 (1978), S. 43-52 
    Details
    ISSN: 1432-1254
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geography , Physics
    Notes: Abstract The effects of small negative air ions on the oxygen uptake of isolated mouse liver cells were studied by exposing the liver cells to varying ion concentrations. For concentrations of the order of 1–2 × 105 ions/cm3, the oxygen uptake was always higher than in the normal atmospheric conditions of 3–8 × 102/ions/cm3. For intermediate concentrations varying effects of activation and inhibition were observed. A statistical analysis showed that the oxygen uptake increased by approximately 14% when liver cells were exposed to ion concentrations of values 1–9 times the normal, by approximately 9% when exposed to 10–99 times the normal, and by approximately 38% when exposed to 100–999 times the normal. The significance and possible implications of the results are discussed.
