Calculates fire severity as the loss of pre-fire to post-fire biomass (in absolute and percentual terms).
calcSeverityB(cohortData, burnedPixelCohortData)A data.table with columns: pixelGroup, ecoregionGroup,
speciesCode, and optionally age, B, mortality, aNPPAct, and sumB.
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.
data.table with columns pixelIndex,
pixelGroup and severityB (absolute biomass lost)
and severityPropB (proportion of biomass lost)
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)
