LightResponseCurveFitter predictLRC

Description

Light Response Function

Usage

LightResponseCurveFitter_predictLRC(theta, 
    Rg, VPD, Temp, VPD0 = 10, fixVPD = (k == 
        0), TRef = 15)

Arguments

theta	numeric vector of parameters
Rg	ppfd [numeric] -> photosynthetic flux density [umol / m2 / s] or Global Radiation
VPD	VPD [numeric] -> Vapor Pressure Deficit [hPa]
Temp	Temp [degC] -> Temperature [degC]
VPD0	VPD0 [hPa] -> Parameters VPD0 fixed to 10 hPa according to Lasslop et al 2010
fixVPD	boolean scalar or vector of nrow theta: fixVPD if TRUE the VPD effect is not considered and VPD is not part of the computation
TRef	numeric scalar of Temperature (degree Celsius) for reference respiration RRef

Details

Predict ecosystem fluxes (Reco, GPP, NEP = GPP-Reco) for given parameters and environmental conditions.

The VPD effect is included according to Lasslop et al., 2010.

If theta is a matrix, a different row of parameters is used for different entries of other inputs
