Smoke Management

Aggressive wildfire suppression during the last century created unexpected side effects. Many ecosystems
accumulated unnaturally high densities of vegetation, giving rise to infestations of non-native plants and insects as well
as the increased susceptibility of native species to disease. And when it invariably returns, conflagration by fire. Federal
Land Managers face the immense challenge of protecting human health and air quality while restoring fire-dependent lands to
their more natural conditions. State of the art meteorological information and computer modeling combine with real-time smoke concentration
data to help address this challenge, allowing the Forest Service to better accomplish prescribed burning targets, increase
safety, and burn cleaner to avoid greater air quality impacts. |

In 2001, under the National Fire
Plan, the US Forest Service initiated six Fire Consortia for Advanced Modeling of Meteorology and Smoke (FCAMMS) in Athens,
CO, East Lansing, MI, Fort Collins, CO, Missoula, MT, Riverside, CA and Seattle, WA. ·
FCAMMS are research and development activities collaborating
across all land management agencies, NOAA, NASA, and universities; which will support firefighters by developing and disseminating
high-resolution fire weather, fire danger, fire behavior and smoke management products. ·
FCAMMS products merge the most advanced science in weather
forecasting and satellite observation with contemporary models and developing fire science to increase the accuracy and precision
of information used by fire weather forecasters and fire intelligence officers to control wildfires quickly and mange fires
efficiently. ·
FCAMMS smoke management products are designed for public health
and air regulatory officials to inform people and evaluate impacts from wildfire and prescribed fire on air quality in communities.
Effective smoke management is a necessary component of fuel treatment programs, especially when sensitive communities are
downwind.

Recent experiences linking drought,
forest health and devastating wildfires have convinced the public to support a National Fire Plan (NFP). Critical to accomplishing
the NFP goal of delivering the highest firefighting productivity at the lowest cost is weather information about fire danger,
fire behavior and smoke dispersion. Over the past few years three technologies used to generate weather-based information
have made substantial advances: satellites remotely sensing in atmosphere and land characteristics, weather forecast models,
and high speed computers facilitating both modeling and communications. While the spot fire weather forecast
is the responsibility of Weather Service forecasters and Geographic Coordination Centers (GAC) meteorologists, FCAMMS
can improve the technology used to develop these forecasts. FCAMMS will collaborate with NOAA and universities to deliver
dependable, timely, high-resolution (12 km or better) meteorological simulations of the wind, temperature, humidity and precipitation.
This information will advance our understanding of interactions between fire, fuels, weather, and topography that ultimately
improving the intelligence fire fighters and fire planners need to advance fire-fighting efficiency. FCAMMS are built on the premise of collaborating
with other federal agencies and universities who have expertise in satellite remote sensing, advanced computing, and weather
forecasting. Each separate FCAMMS involves consortia of collaborating groups with Forest Service researchers and other land
manager personnel working side by side to learn, apply, and develop the most relevant technologies. |

FCAMMS Products High-resolution weather information:
While the Weather Service continually upgrades observational and model data for its forecasters, access to local high-resolution
model results can provide firefighters with a more detailed wind profiles around topographic features. Fire indices: Researchers have developed
a set of indices useful for forecasting fire weather. FCAMMS output of 4km, resolution Haines index is one example of a useful
fire index. Daily Fire Maps: The USFS Rocky
Mountain Research Station Fire Sciences Laboratory has developed daily maps of active fire locations in most of the continental
U.S. with 1 km x 1 km resolution. The maps are derived using the real-time satellite images of NASA Terra and Aqua satellites.
