Light Response Function

Source: R/LRC_base_optim.R

Predicts the Net Ecosystem Production (NEP), Ecosystem Respiration (Reco) and Gross Primary Production (GPP) based on the Light Response Function.

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

Arguments

theta

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

Rg

photosynthetic flux density mumol / m2 / s or Global Radiation.

VPD

Vapor Pressure Deficit hPa

Temp

Temperature degC

VPD0

hPa, Parameters VPD0 fixed to 10 hPa according to Lasslop et al 2010

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

Value

  • NEP: Net ecosystem production (-NEE), vector of length(Rg)

  • Reco: Ecosystem respiration

  • GPP: Gross primary production

Details

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