An inverse modelling approach based on trajectories and daily measurements of airborne sulfate at 13 background stations during one year is presented. A source-receptor relationship matrix was calculated from the trajectories which are utilised as a first approximation to a full dispersion model. The matrix was inverted with simple constraints (minimising the length and the Laplacian of the solution). Major emission areas in Europe (black triangle, England, Northern Italy, Kola) were reproduced qualitatively by this method. It is an alternative to trajectory statistics as well as a first step towards regional-scale inverse modelling of sources of atmospheric trace constituents. A test with idealised synthetic observations corroborated the high potential of this method.
