R Documentation

Calculate fire severity

Description

Calculates fire severity as the loss of pre-fire to post-fire biomass (in absolute and percentual terms).

Usage

calcSeverityB(cohortData, burnedPixelCohortData)

Arguments

`cohortData`	A `data.table` with columns: `pixelGroup`, `ecoregionGroup`, `speciesCode`, and optionally `age`, `B`, `mortality`, `aNPPAct`, and `sumB`.
`burnedPixelCohortData`	An expanded `cohortData` `data.table` with pixel-level cohort information on burnt pixels and the following (optional) columns: `severity` - fire severity in that pixel calculated based on fire behaviour properties; `firetolerance` - species-level fire tolerance; `severityToleranceDif` - the difference between `severity` and `firetolerance`.

Value

data.table with columns pixelIndex, pixelGroup and severityB (absolute biomass lost) and severityPropB (proportion of biomass lost)

Note

if burnedPixelCohortData does not have a B column, the fire is assumed to be stand replacing (i.e. we assume B to be 0 across all pixels/cohorts in burnedPixelCohortData)
