DUSTRAN is a comprehensive dispersion modeling system consisting of a dust-emission module, a diagnostic meteorological model, and dispersion models that are integrated seamlessly into a geographic information system (GIS) interface. The dust emissions module calculates emissions for explicit size classes from both active (e.g. vehicular) and natural (e.g. wind-blown) sources. Users can interactively create a release scenario using data layering that displays the model domain, sources, and results as well as other spatial and geophysical data sources to aid in analyzing and interpreting the scenario.

This User's Guide documents the technical aspects of the modeling system and includes installation instructions, and detailed example tutorials.
