Development of the DUSTRAN GIS-Based Complex Terrain Model for Atmospheric Dust Dispersion

摘要

The verified and documented dust dispersion modeling system (DUST TRANsport or DUSTRAN) was developed to address particulate air quality issues at military training ranges from fugitive dust sources. This development effort was funded by the Strategic Environmental Research and Development Program (SERDP) with partial funding from the US Environmental Protection Agency (EPA) and the Forest Service to extend DUSTRAN to address their issues related to the 'off-target' drift of aerially applied pesticides. DUSTRAN is based on widely- used atmospheric models and model components. The modeling system efficiently couples these modeling components and advances the state-of-science in dust- emission formulations based on SERDP-funded field studies (Projects SI-1191 and SI-1399) for determining dust emission factors from vehicle activities. DUSTRAN is based on a commercially available geographic information system (GIS) and EPA-approved atmospheric dispersion models. DUSTRAN also includes formulations for estimating particulate concentrations from wind-generated dust emissions.
