Measurement of Space Charge Density Over Flat Ground in Nearly Neutral Stratified Atmospheric Surface Layer
Year: 1997
Type: article
Abstract: Space charge density and a-activity profiles were measured simultaneously at a 0-1.6 m layer above the ground.Measurements were obtained with one instrument to measure a-activity profile and with two Obolensky filters to measure space charge density where one Obolensky filter was used as a reference instrument.Theoretical space charge profiles were calculated with the electrode effect model given by Tuomi (1982) and they were compared with experimental 'profiles measured.From the analysis of the recordings, the electrode ef feet was observed.The agreement between theoretical and experimental results has been discussed.Best agreement between the theoretical and experimental results was obtained for the height variation between 0. 2-0.8 m when the ionization rate is constant.
