The Atmospheric Transport and Dispersion Model ATAD is oriented toward transport and dispersion studies. It can calculate trajectories of 5-days duration either forward or backward in time at 6-hour intervals during any selected period for any number of requested locations. The individual trajectories are calculated using transport winds averaged in a vertical layer. There are various optional and standard output characteristics. They include tables of transport layer depth, maximum vertical wind shear, trajectory positions, trajectory plots, and surface air concentrations. This program was developed for an IBM 4341 computer using the OS operating system.
