A transport rno<leÌ for the estimation of tracers spreading from biomass Ìlrrning areas Ììas been developed on the basis of the semi-Lagrangian technique. l'hc rnõdel consists of a three-dimerrsional Lagrangian form transport equation for rracers ancl uses the quasi-rnonotonc locaì cubic-spline interpoÌation for calculation ,rf lnknown values at irregular points. A mass-conserving property of the model is 5asccl on the flux-corrected transport method using the aÌgorithm of Priestley. The transport of the smoke particles frorn Amazonia was simulated for the period from August 20 to 29,1995. During tÌris period the air mass iocated below 2 km movecl to ihe south and carried the smoke particles until 30"S.
