A transport model for the estimation of tracers spreading from biomass burning areas has been developed on the basis of the semi‐Lagrangian technique. The model consists of a three‐dimensional Lagrangian form transport equation for tracers and uses the quasi‐monotone local cubic‐spline interpolation for calculation of unknown values at irregular points. A mass‐conserving property of the model is based on the flux‐corrected transport method using the algorithm of Priestley. The transport of the smoke particles from Amazonia was simulated for the period from August 20 to 29, 1995. During this period the air mass located below 2 km moved to the south and carried the smoke particles until 30°S.
