A special type of Lagrangian model, where the trajectory of the center of gravity of a diffusing cloud is computed first and then the diffusion with respect to this center of gravity is taken into account. Again, large computational effort is required for a multiple source model.

On a utilisé deux modèles de dispersion : le modèle Lagrangien et le modèle par Trajectoires. Bien que ces deux modèles soient basés sur les mêmes équations, hypothèses et approximations, le modèle par Trajectoires est destiné à estimer les effets produits par les émissions d'un pays quelconque sur les concentrations et les dépôts d'un autre pays.

In order to predict the atmospheric concentrations of sulphur dioxide and sulphates down wind of source regions several phenomena must be quantitatively accounted for: 1. atmospheric transport and diffusion [;] 2. precipitation scavenging [;] 3. dry deposition at the earth's surface [;] 4. conversion of SO2 to sulphates. The simplest approach to solving this problem uses a "trajectory box model" with appropriate parameterization of items 2 to 4 above. This type of model has been applied in Europe and is presently being adopted to the North American scene by the Atmospheric Environment Service.

Quantitative modelling, especially computer simulation modelling, appears to be used on a somewhat regular basis in certain specific aspects of environmental impact assessments. ... For example, computerized slick trajectory models are commonly employed for predicting the movement of accidental oil spills in the marine environment. Another common application is for the prediction of air quality and of the fate of aerially discharged emissions.
