Sažetak

Revisions to the dry deposition scheme in the Lagrangian dispersion model, NAME are described. Improvements are
made for situations where material is not well mixed within the boundary layer and for sedimenting heavy particles. The revised
scheme overcomes computational noise, common in Lagrangian dispersion models, with a manageable or no increase to the
computational cost. The result is a scheme which is well suited to all situations and which has better interaction between the
advection (mean and turbulent), deposition and sedimentation.
