The assembly performs the method for monitoring and predicting gaseous pollutant cloud drift and dispersion across complex terrain resulting from the site a source or potential source of pollution. Cloud drift and dispersion simulation information is produced for the earth surface terrain site under a wide range of simulated atmospheric conditions. The cloud drift and dispersion simulation information is then recorded and stored for later retrieval. The prevailing environmental conditions are monitored at the actual terrain site. As the time for the formation of a cloud of material such as an exhaust plume of a flight vehicle or movement of toxic gas is anticipated, information is selected from the recorded drift and dispersion simulation information in response to the preselected environmental conditions monitored at the actual terrain site. Thus, the selected information is displayed to predict and monitor the cloud drift and dispension at the actual terrain site on a real-time basis under prevailing environmental conditions. In a specific embodiment, an interactive video display mechanism is responsive to the prevailing environmental atmospheric conditions at the actual terrain site for displaying selected video images of simulated cloud drift and dispersion information.
