A local predictive model developed by Gary Achtemeier and the USFS to evaluate the low-level transport of smoke particles and fog potential associated with smoldering combustion

The underlying premise behind the model computations is to determine the state and activity of the surface drainage flow—a flow regime that develops as part of the broader mountain-valley circulation over moderate to steep terrain

Under relatively weak large-scale weather conditions the nocturnal boundary layer thermally decouples from larger-scale influence

Under this scenario, in the presence of smoldering combustion, the local meteorological conditions surround and mix with the residual fire environment—the PB-Piedmont model has been designed to evaluate this scenario, including the thermodynamics and particle transport that ensue
