In REddyProc: Post Processing of (Half-)Hourly Eddy-Covariance Measurements

RHLightResponseCostC

Description

Computing residual sum of squares for predictions vs. data of NEE implemented in C. See LightResponseCurveFitter_computeCost for a description.

Usage

RHLightResponseCostC(theta, flux, sdFlux,
    parameterPrior, sdParameterPrior, Rg,
    VPD, Temp, VPD0, fixVPD)

Arguments

theta	parameter vector with positions as in argument of LightResponseCurveFitter_getParameterNames
flux	numeric: NEP (-NEE) or GPP time series [umolCO2 / m2 / s], should not contain NA
sdFlux	numeric: standard deviation of Flux [umolCO2 / m2 / s], should not contain NA
parameterPrior	numeric vector along theta: prior estimate of parameter (range of values)
sdParameterPrior	standard deviation of parameterPrior
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
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
