A segment approach is presented that allows to describe the temporal evolution of the dispersion of passive pollutants in non-stationary meteorological conditions. The methodology consists of a continuous series of source emissions integrated in time intervals whose result is a plume segment and has no numerical inversion, which refines earlier literature approaches. The dispersion of pollutants is subject to advection in horizontal direction and turbulent diffusion in all three directions, in an inhomogeneous and non-stationary atmospheric boundary layer. For validation, data from the Copenhagen experiment were used, but with a greater time resolution, considering meteorological data with 10 minutes averaged value. The numerical results show that the experimental data and other models from literature are compatible.
