Abstract
The development of the MESOPUFF II regional-scale air quality model is described. MESOPUFF II is a Lagrangian variable-trajectory puff superposition model suitable for modeling the transport, diffusion and removal of air pollutants from multiple point and area sources at transport distances beyond the range of conventional straight-line Gaussian plume models. It is an extensively modified version of the MESOscale PUFF (MESOPUFF) model. Major additions and enhancements include: use of hourly surface meteorological data and twice-daily rawinsonde data; separate wind fields to represent flow within and above the boundary layer; parameterization of vertical dispersion in terms of micrometeorological turbulence variables; parameterization of SO2 to SO4(-2) and NOx to NO3(-1) conversion, including the chemical equilibrium of the HNO3/NH3/NH4NO3 system; resistance modeling of dry deposition, including options for source or surface depletion; time- and space-varying wet removal; and a computationally efficient puff sampling function. The scientific and operational bases for these developments are described. The results of a preliminary evaluation of several model algorithms during a two-day period of the Tennessee Plume Study are also presented.
