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
