چکیده

The southeastern United States – states extending from Virginia to Texas and from the Ohio River southward – (hereafter called the “South”) comprise one of the most productive forested areas in the United States. Although the South represents only 24 percent of the U.S. land area, approximately 200 million acres (81 million ha) or 40 percent of the Nation’s forests lie within this region (SRFRR, 1996).

Sensitivity of air quality simulation to smoke plume rise

Plume rise is the height smoke plumes can reach. This information is needed by air quality models such as the Community Multiscale Air Quality (CMAQ) model to simulate physical and chemical processes of point-source fire emissions. This study seeks to understand the importance of plume rise to CMAQ air quality simulation of prescribed burning to plume rise. CMAQ simulations are compared between...

Southern Smoke Simulation System - a framework for modeling smoke impacts from prescribed burning in the South

Fire is a natural disturbance in many ecosystems, although one that can have adverse impacts, particularly to nearby communities. Prescribed fire is an important tool for land managers as its judicious use can allow fire back into ecosystems to perform its essential role in maintaining ecosystem health and function while minimizing adverse impacts on the local community. Smoke is the prime adve...

Developing a near real-time regional system for modeling air quality impacts of prescribed fire

Emissions from wildland fires are becoming of increasing importance with recent changes to air quality regulations regarding PM2.5 concentrations and regional haze. Wildfire reporting is fairly well handled, especially when compared with the reporting of prescribed fire activities. Information on prescribed fire emissions ranges from good to nonexistent. With states developing/implementing Smok...

Modeling natural emissions in the Community Multiscale Air Quality (CMAQ) Model–I: building an emissions data base

A natural emissions inventory for the continental United States and surrounding territories is needed in order to use the US Environmental Protection Agency Community Multiscale Air Quality (CMAQ) Model for simulating natural air quality. The CMAQ air modeling system (including the Sparse Matrix Operator Kernel Emissions (SMOKE) emissions processing system) currently estimates non-methane volat...

Modeling Smoke Plume-Rise and Dispersion from Southern United States Prescribed Burns with Daysmoke

We present Daysmoke, an empirical-statistical plume rise and dispersion model for simulating smoke from prescribed burns. Prescribed fires are characterized by complex plume structure including multiple-core updrafts which makes modeling with simple plume models difficult. Daysmoke accounts for plume structure in a three-dimensional veering/sheering atmospheric environment, multiple-core updraf...
