FDMpro™ is an air quality model specifically designed for computing concentration and deposition impacts from fugitive dust sources. The model is based on the concept of US EPA Fugitive Dust Model (FDM) and CALINE. It can be used to model non-buoyant point, line and area sources. The model is generally based on the well-known Gaussian Plume formulation for computing concentrations, but the model has been specifically adapted to incorporate an improved gradient-transfer deposition algorithm.
