NOAA Technical Memorandum ERL ARL-63,  December 1976


Abstract - A finite difference method for vertical diffusion and deposition has been developed and incorporated into the existing ARL trajectory model.  The finite difference multi-box model permits temporal variations of vertical diffusivity profiles and deposition parameters.  The multi-box model is presented including some examples of its application to Lagrangian trajectories with respect to dry deposition and diurnal stability changes.
