A source-receptor model, derived with a few modifications from the algorithm developed by Stohl in 1996, has been applied for assessing the locations of emission sources of airborne tracers. In this paper, the model sensitivity to the number of receptor points and iterations needed to reconstruct a reliable picture of spatial position of tracer sources has been assessed. This has been done by simulating some sets of schematic air trajectories, and assigning a priori both the position of some sources in given cells of a horizontal grid, and the atmospheric concentrations of the tracer associated to each trajectory crossing pre-assigned receptor points. The conditions allowing the model to locate correctly the sources, together with a useful rule for dealing with the grid cells crossed by a limited number of trajectories, have been established.
