Estimating air quality impacts from haul roads has presented many challenges to air dispersion modelers over the years. From the lack of a true line source to high degrees of variability in emissions estimates, consistent guidance was minimal and confusion was high. Previous releases of AERMOD View sought to reduce some of that confusion by adding tools for modelers such as the Line Volume source. While the AERMOD and ISC models do not contain true line sources, the Line Volume source allowed modelers to easily create a series of volume sources along a path. This source type made it quick and easy to add large sets of volume sources thus reducing time and effort.

The CALPUFF model can use three-dimensional meteorological fields developed by the CALMET model from prognostic and observational data. These spatially-varying meteorological variables can transform puffs as the model calculates concentrations and deposition fluxes.

The AERMOD model has long had a non-default option to run in screening mode. In this mode, the calculations are performed with the plume centerline falling on top of each individual receptor.
