MPTDS: Multiple Point Gaussian Dispersion Algorithm with optional terrain adjustment

The model is a completion of the air pollution program MPTER that includes dry deposition and sedimentation and thus can be applied to heavy gases and particulate matter. It works in urban or rural areas, with flat terrain (altitute below the emission source) and point sources. It may work both on short (1 hour) or long (1 year) time intervals.
