Contains the manual intended for use with the interactive FireSmart disc (manual also included on interactive disc). Structure of the Canadian Forest Fire Weather Index (FWI) system. (1998). As climate warming stokes longer fire seasons and more severe fires in the North American boreal forest, being able to calculate how much carbon each fire burns grows more urgent. gives an indication of fuel consumption in moderate duff layers and medium-size The Canadian Forest Fire Weather Index (FWI) System was first issued in 1970 after several years' work by a number of fire researchers in the Canadian Forestry Service. The initiation of crown fires in conifer stands was modelled through logistic regression analysis by considering as independent variables a basic physical descriptor of the fuel complex structure and selected components of the Canadian Forest Fire Weather Index (FWI) System.

Forestry Technical Report 35. Canadian Forest Service. Van Wagner, CE. (1989) Prediction of crown fire behaviour in conifer stands. The Fire Weather Index was originally proposed by Van Wagner for the wildfire prevention in Canadian forests; it is calculated from a set of weather parameters and describes the evolution of the current moisture content of different fuel layers of the forest system, together with the influence of wind in fire propagation. Fire on peatlands takes place not only in areas where preparation for cultivation is in progress, but also in areas that have been cultivated, such as for sago palm growing. The FWI is now the forecast tool of choice in Europe in the shape of the European Forest Fire Information System (EFFIS). Many global regions have reported increasing fire activity in recent decades, which is attributed to numerous factors such as climate change-altered fire regimes, rural-urban population shifts, and land use change affecting vegetation and fuel conditions.

Unlike most other fire danger indices or codes that operate on gravimetric moisture content and use the logarithmic drying equation to represent diffusion, the DC is based on a model that balances … Presented in tabular format, this guide provides a simplified version of the system and is designed to assist field staff in making approximations of FBP System outputs. Van Wagner, C.E. fireDanger is an R package for the Implementation of the Canadian Fire Weather Index System using as input seasonal forecast data and other climatic datasets. The Drought Code (DC) is a numeric rating of the average moisture content The Canadian Forest Fire Weather Index (FWI) System consists of six components that account for the effects of fuel moisture and weather conditions on fire behavior.
