Logistic Sigmoid Light Response function for GPP
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
