Description

Burn probability calculation for wildland fire FSIM

Reference

source_ref: WildlandFire.jl/src/fsim.jl:231 Burn probability calculation for wildland fire FSIM

Parameters

Name	Units	Default	Description
`N_burned`			Number of times cell burned in simulation (dimensionless)
`A_FPU`			Total Fire Planning Unit area
`N_years`			Total number of simulated years (dimensionless)
`P_FL_given_burn`			Conditional probability of flame length category given burning (dimensionless)
`A_burned`			Total area burned across all simulated years

Observed

Name	Units	Default	Description
`BP_conditional`			Conditional burn probability at given flame length (dimensionless)
`BP_FPU`			FPU-level annual burn probability (dimensionless)
`BP`			Cell-level annual burn probability (dimensionless)

Observed expressions

$$ BP_{conditional} = BP \cdot P_{FL\,given\,burn} $$

Conditional burn probability at given flame length (dimensionless)

$$ BP_{FPU} = \frac{A_{burned}}{A_{FPU} \cdot N_{years}} $$

FPU-level annual burn probability (dimensionless)

$$ BP = \frac{N_{burned}}{N_{years}} $$

Cell-level annual burn probability (dimensionless)
