fireHazard: Fire hazard

Description

Estimates potential fire behaviour at each daily step of a simulation

Usage

fireHazard(x, SpParams, forest = NULL, standardConditions = FALSE, 
           freq="days", fun = "max")

Value

A matrix with fire behaviour variables (columns) for each simulated day (rows) or coarser time steps if summaries are requested.

Arguments

x

An object of class spwb, spwb_day, pwb, growth, growth_day or fordyn.

SpParams

A data frame with species parameters (see SpParamsDefinition and SpParamsMED).

forest

An object of class forest (needed if x is not of class fordyn).

standardConditions

A flag to indicate that standard fire weather conditions are to be used (instead of deriving fuel moisture and windspeed from x).

freq

Frequency of summary statistics (see cut.Date).

fun

Summary function (by default, maximum values).

Details

Live fuel moisture of shrub and canopy layers is estimated from plant water status. Dead fuel moisture is estimated following Resco-de-Dios et al. (2015).

Examples

if (FALSE) {
#Load example daily meteorological data
data(examplemeteo)

#Load example plot plant data
data(exampleforestMED)

#Default species parameterization
data(SpParamsMED)

#Initialize soil with default soil params (4 layers)
examplesoil = soil(defaultSoilParams(4))

#Initialize control parameters
control = defaultControl("Granier")

#Initialize input
x1 = forest2spwbInput(exampleforestMED,examplesoil, SpParamsMED, control)

#Call simulation function
S1<-spwb(x1, examplemeteo, latitude = 41.82592, elevation = 100)

#Evaluate fire hazard
F1 <-fireHazard(S1, SpParamsMED, exampleforestMED)
