摘要：
Prescribed burning plumes are not sufficiently resolved in current modeling systems; therefore, their regional impacts cannot be accurately predicted. A modeling, system is being developed to better characterize the emissions from the burns and the dispersion and chemical transformation of the smoke plumes. Adaptive grids are used to increase the resolution of regional-scale models and a Lagrangian plume model is employed to model the sub-grid scale plume dynamics. Simulations of a prescribed burn conducted at Fort Benning, Georgia on 9 April 2008 show that the new system significantly improves the predictions of downwind pollutant levels over conventional modeling systems
