Title: Development of Modeling Tools for Predicting Smoke Dispersion from Low-Intensity Fires

Project Proposal Abstract: Predicting the dispersion of smoke from low-intensity fires is particularly challenging because it is highly sensitive to near-surface meteorological conditions, local topography, vegetation, and atmospheric turbulence within and above vegetation layers. Existing integrated smoke dispersion modeling systems, which are designed for predictions of smoke from multiple sources on a regional scale, do not have the necessary resolution to accurately capture smoke from low-intensity fires that tends to meander around the source and may stay underneath forest canopies for a relatively long period of time. Simple dispersion models, which quite often are location specific, are limited by their simplistic nature in treating the emissions source, topography, canopy, and the atmospheric conditions. The primary goal of our project is to build a smoke management tool specifically for low-intensity fires by taking advantage of recent developments in fine-scale atmospheric dispersion modeling and in computational fluid dynamics (CFD) modeling. Specifically, we will 1) evaluate several state-of-the art, fine-scale atmospheric dispersion models and CFD models with emphasis on their performance in simulating local-scale flows and near-surface conditions including the conditions within forest canopies; the evaluation will use existing data and new data from low-intensity prescribed fires; 2) adapt, modify, and implement a fine-scale atmospheric dispersion model with a detailed canopy sub-model for use in predicting smoke dispersion from low-intensity fires; 3) improve our understanding of the influence of forest vegetation layers and local terrain-induced circulations on smoke emissions, meandering, dispersion, and transport within and above forest canopies; and 4) develop web-based, user friendly decision support tools for land managers, air quality regulators, and farmers for planning prescribed burns. The proposed work presents a cost-effective way to build a much needed tool for smoke management by taking advantage of the rapid advancement in fine-scale atmospheric dispersion modeling for emergency response in the post 9-11 era. Since the tool will be location-independent, it would benefit land managers worldwide.
