Abstract
Concentrations of positive and negative ions that are generated in the ambient air at a selected location are controlled in time-varying manner. Apparatus for generating air ions includes controllable high voltage sources and electrodes connected to the sources adapted to generate positive ions and negative ions in ambient air near the electrodes. Control circuitry is coupled to the high voltage sources to control the voltage levels at the electrodes for altering the quantities of positive ions and/or negative ions that are generated in time-varying manner within the ambient air about the electrodes. The control circuitry may control the voltage sources to generate a simulated ion signature of variations in ion concentrations as detected at a selected geographic location.
