LogisticSigmoidLRCFitter predictGPP
Description
Logistic Sigmoid Light Response function for GPP
Usage
LogisticSigmoidLRCFitter_predictGPP(Rg, Amax,
alpha)Arguments
Rg |
ppfd [numeric] -> photosynthetic flux density [mumol / m2 / s] or Global Radiation |
Amax |
vector of length(Rg): saturation (beta parameter) adjusted for effect of VPD for each line of Rg |
alpha |
numeric scalar or vector of length(Rg): alpha parameter: slope at Rg = 0 |
Details
GPP <- Amax * tanh(alpha * Rg / Amax)
Value
numeric vector of length(Rg) of GPP
