Lagrangian models are models in which parcels of air are followed as they blow with the wind. The models keep track of the pollutant content of the parcels. This is in contrast to Eulerian models, where the integration of the mass-balance equation is performed in a geographically fixed grid. Lagrangian models are popular, because their basic principle is easy to grasp also for nonprofessionals. In addition some numerical problems associated with the advection terms in the Eulerian mass-balance equation are avoided by Lagrangian models.
