Title: Evaluation and Improvement of Smoke Plume Rise Modeling

Project Proposal Abstract: Regional smoke and air quality models require plume rise information (the height of smoke plumes and vertical distribution of smoke particles) as initial and boundary conditions in modeling point-source emissions like wildland fires. A unrealistic specification of plume rise will lead to incorrect simulation and prediction in the direction and rate of horizontal smoke transport and dispersion, and in spatial patterns of regional pollutant distribution due to large vertical variability in winds and turbulence intensity. The purpose of this study is to evaluate and improve the performance of Daysmoke, a plume rise model, and to understand the significance for regional smoke and air quality modeling. The research objectives to be achieved include (1) evaluating plume rise estimates from Daysmoke and comparing with other models using field measurements, (2) improving accuracy and feasibility of Daysmoke, (3) evaluating and analyzing uncertainty in regional smoke and air quality modeling due to plume rise calculation, and (4) transferring research products into field application tools. A combined approach of field measurement, numerical modeling, and dynamical and statistical analysis will be used to obtain data, conduct simulation and evaluation, and improve model. The expected products include datasets of smoke measurements (plume rise, vertical profiles of smoke particles, ground PM2.5 and O3, smoke plume satellite remote sensing, and meteorological conditions), improved dynamic Daysmoke and a new static Daysmoke, case and statistical evaluation results of Daysmoke and other plume rise models, valuation results of uncertainty and improvements in regional smoke and air quality modeling, and Web and GIS supported Daysmoke. These products are expected to provide fire and air quality managers and modelers with quantitative information and tools for understanding the accuracy, limits, and uncertainty in plume rise calculation, and their impacts on simulation and prediction of regional smoke transport and air quality effects.
