The use of charged particles as markers to simulate the transport of neutrally buoyant contaminants within puffs and plumes within the atmosphere is an established technique [1]. In this paper the use of a bipolar space charge method is discussed. The main advantage of this method over the use of unipolar space charge is avoidance of the difficulties encountered with the self repulsion of unipolar ions, although recombination now becomes an effect that must be allowed for.
