“…In addition, from the experience gained from model validation against tracer gas dispersion experiments inaccuracies in the modelling procedure could account for a further factor of 10 [cf. 16,24,25,32]. Finally, the factor that is least clear in modelling the airborne spread of FMD is the probability of infection of animals under a plume.…”

The application of a computer model called Rimpuff for simulating the airborne spread of foot-and-mouth disease (FMD) is described. Rimpuff is more sophisticated and accurate than other FMD simulation models previously described. It can be run on a desktop computer and performs analyses very quickly. It can be linked to a geographical information system and so the information generated can be integrated with geographical and demographical data for display in a format that can be easily assimilated and transmitted electronically. The system was validated using historical data from outbreaks of FMD in France and the UK in 1981, and from Denmark and the former German Democratic Republic (GDR) in 1982. A very good fit was obtained between the direction of the plumes of virus simulated by the model and the spread of disease from France to the UK in 1981. Although cattle in the UK were infected during the episode, the concentrations of airborne virus in the plumes simulated by the model were beneath the infectivity threshold for cattle. It was concluded from the analysis that the number of pigs infected in France, and therefore the source concentration of airborne virus, was probably much higher than was recorded at the time of the outbreaks. Analysis of the Denmark/GDR episode pointed to the possibility that the source of virus for the 1982 epidemic in Denmark could have been one or more unreported outbreaks involving pigs in the former GDR.

The study of atmospheric dispersion has become increasingly important over the last 120 years or so. Research in exposure pathways, fate of pollutants, dispersion model evaluation and validation are all reliant on experimental data. The most common atmospheric tracer compounds in use at the present time are the cyclic perfluoroalkanes and sulphur hexafluoride. These compounds are non-toxic, nonreactive and have low atmospheric background concentrations although they are recognized as greenhouse gases. This review discusses their use relative to other tracer species. A brief history of their individual analyses is included. The review then seeks to give a concise description of some representative atmospheric tracer dispersion experiments in terms of range, duration and objectives, and tracers used. Concluding remarks relating to the future use of these species are also presented.

A novel approach to atmospheric dispersion modelling: The Puff‐Particle Model

SUMMARYThe Puff-Particle Model (PPM) uses a new approach to problems of three-dimensional atmospheric dispersion from micro-to mesoscale. The pollutant particles are grouped in clusters treated as Gaussian puffs, which are dispersed making use of the concept of relative diffusion. The centre of mass of each puff is moved along a stochastic trajectory. This trajectory is derived from particle trajectories given by a Lagrangian stochastic-dispersion model. In this way, the PPM retains the advantages of traditional puff models and those of particle models, and is able to take into account the correct probability density function of the stochastic velocity components. The effect of meandering (caused by turbulent eddies larger than the puff but not resolved by the flow field) is simulated by the puff centre trajectories, yielding a complete description of dispersion. The PPM is validated using measurements from three tracer experiments in Copenhagen, Lillestr@m and Kincaid.
