“…An often mentioned advantage of Lagrangian trajectory models is their ability to determine contributions at a specified receptor from individual sources (Johnson, 1983). The calculations of longrange transport from trajectory models contain the effects of complex chemical and physical processes.…”

A new approach is proposed to delineate the source-receptor relationship in an Eulerian model. A small, unique oscillatory signal is superimposed on each emission source in the airshed. At receptor sites the concentration time series axe analyzed by a Fourier transform to give the amplitudefrequency spectrum. Distinct peaks found in the spectrum are identified at the emission frequencies.The amplitude of the spectrum at the source frequency represents the individual contribution from that emitter. Various atmospheric transport and diffusion models are solved to show the effects of different physical and chemical processes on the oscillatory signals. Both analytical and numerical solutions are used to demonstrate the performance of the method.

A long range transport model and its application to an Etna plume are described. The model is a classical segmented plume lagrangian trajectory model. Firstly, air mass trajectories are computed by using the actual winds observed at the E.C.M.W.F. (Reading U.K.). The model then determines 5-day trajectories starting every 3 hours and made of 3-hour segments. Vertical movements of air parcels are taken into account by using the vertical component of the synoptic wind. Secondly~ diffusion, S02 to SO4 transformation and dry deposition are calculated for each trajectory segment. Sensitivity tests are presented and the results of the simulation for an experimental field period (21-25 september 1983) are examined.
