The Alaska Reference Database originated as the standalone Alaska Fire Effects Reference Database, a ProCite reference database maintained by former BLM-Alaska Fire Service Fire Ecologist Randi Jandt. It was expanded under a Joint Fire Science Program grant for the FIREHouse project (The Northwest and Alaska Fire Research Clearinghouse). It is now maintained by the Alaska Fire Science Consortium and FRAMES, and is hosted through the FRAMES Resource Catalog. The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Moderate Resolution Imaging Spectroradiometer (MODIS) on board the NASA Earth Observing System Terra and Aqua satellites provides global fire observations of unprecedented quality. This paper presents spatial and temporal distributions of active fires from 2001 and 2002, the…

The fire shelter is an integral part of wildland firefighting Personal Protective Equipment (PPE). There is growing concern, however, that firefighters may accept greater levels of risk while carrying them. Such concerns are consistent with Risk Homeostasis Theory, which…

The classification of savanna fires into headfire and backfire types can in theory help in assessing pollutant emissions to the atmosphere via relative apportionment of the amounts of smouldering and flaming combustion occurring, and is also important when assessing a fire's…

Nationally, the causes and extent of fire on lands administrated by the United States Forest Service varied significantly from 1940 to 2000, with California experiencing the largest relative annual burned areas. The south-east and California experienced the largest relative area…

Fire affects entire ecosystems - their flora, fauna, the atmosphere and soil. Research on the effects of fire to date has focussed primarily on the former three, whereas effects on the soil system have seen less attention. Burning and resulting post-fire environmental conditions…

Fire risk in western North America has increased with increasing cover of Bromus tectorum, an invasive alien annual grass. The relationship between B. tectorum cover and fire risk was determined in a historically burned Artemisia tridentata-Poa secunda shrub?steppe community…

This paper presents an experimental method using computer-based image processing techniques of visual and infrared movies of a propagating fire front, taken from one or more cameras, to supply the time evolutions of the fire front shape and position, flame inclination angle,…

Firebrands or embers are produced as trees and structures burn in wildland-urban interface (WUI) fires. It is believed that firebrand showers created in WUI fires may ignite vegetation and mulch located near homes and structures. This, in turn, may lead to ignition of homes and…

Fluxes of water vapor, heat, and carbon dioxide associated with a prescribed grass fire were documented quantitatively using a 43-m instrumented flux tower within the burn perimeter and a tethered balloon sounding system immediately downwind of the fire. The measurements…

The concept of fire line rotation was applied to curved fire line elements like those of a point ignition fire in a slope or in a wind field. Convective effects induced by the fire modify the shape of the flame around its perimeter and affect the propagation of the fire front.…

Descriptions of fuels and their quantification are used in several aspects of forest management and research. However, collecting site-specific data can be tedious, time-consuming, and expensive. Fuel photo guides, with their pictorial catalogs and accompanying fuel descriptions…

The Haines Index is an operational tool for evaluating the potential contribution of dry, unstable air to the development of large or erratic plume-dominated wildfires. The index has three variants related to surface elevation, and is calculated from temperature and humidity…

Wildland fire research has historically orbited around a physical paradigm of fire. This strategy has yielded remarkable results, yet increasingly it cannot speak to the core issues that concern fire management. Two additional paradigms are needed. One would build on fire's…

It is shown that the shape of the fire perimeter is not always a regular line. In flank or down-slope fires, the fire line can assume a zigzag shape with kinks at practically orthogonal angles. These kinks are associated with convection cells that generate local equilibrium…

A numerical model of heat transfer in dry soil was developed to predict temperatures and depth of lethal heat penetration during cone calorimeter tests used to simulate wildland fire exposures. The model was used to compare predictions made using constant and temperature-…

The effects of wind and topographic slope are important considerations when determining the rate and direction of spread of wildfires. Accordingly, most models used to predict the direction and rate of spread contain components designed to account for these effects. Over the…

The maximum solar elevation is typically less than 50 degrees in the Alaskan boreal region and solar elevation varies substantially during the growing season. Because of the relatively low solar elevation at boreal latitudes, the effect of topography on spectral reflectance can…

We develop empirical models for the rate of spread and intensity of fires in grass fuels. The models are based on a well-known physical analogy for the rate of spread of a fire through a continuous fuelbed. Unlike other models based on this analogy, we do not attempt to directly…

Several recent papers have suggested replacing the terminology of fire intensity and fire severity. Part of the problem with fire intensity is that it is sometimes used incorrectly to describe fire effects, when in fact it is justifiably restricted to measures of energy output.…

The major source of uncertainty in wildfire behavior prediction is the transient behavior of wildfire due to changes in flow in the fire's environment. The changes in flow are dominated by two factors. The first is the interaction or 'coupling' between the fire and the fire-…
