Nonrectangular Light Response function for GPP

LRC_NonRect_predictGPP(Rg, Amax, alpha, conv)

Arguments

Rg

photosynthetic flux density umol / m2 / s or Global Radiation

Amax

saturation (beta parameter) adjusted for effect of VPD

alpha

slope at Rg = 0

conv

convexity parameter (see details)

Value

vector of GPP

Details

This function generalizes the RectangularLRCFitter_predictGPP() by adding the convexity parameter conv. For conv -> 0 (logitconv -> -Inf): approaches the rectangular hyperbolic. For conv -> 1 (logitconv -> + Inf): approaches a step function. Expected values of conv are about 0.7-0.9 (Moffat 2012).
