In REddyProc: Data processing and plotting utilities of (half-)hourly eddy-covariance measurements

Description

Default list of parameters for Lasslop 2010 daytime flux partitioning For highest compatibility to Lasslop10 use nBootUncertainty=0L, isAssociateParmsToMeanOfValids=FALSE , isLasslopPriorsApplied=TRUE, isBoundLowerNEEUncertainty=FALSE , smoothTempSensEstimateAcrossTime=FALSE

Usage

partGLControl(LRCFitConvergenceTolerance = 0.001, nBootUncertainty = 30L, 
    minNRecInDayWindow = 10L, isAssociateParmsToMeanOfValids = TRUE, 
    isLasslopPriorsApplied = FALSE, isSdPredComputed = TRUE, 
    isFilterMeteoQualityFlag = FALSE, isBoundLowerNEEUncertainty = TRUE, 
    smoothTempSensEstimateAcrossTime = TRUE)

Arguments

LRCFitConvergenceTolerance	convergence criterion for LRC fit. If relative improvement of reducing residual sum of squares between predictions and observations is less than this criterion, assume convergence. Decrease to get more precise parameter estimates, Increase for speedup.
nBootUncertainty	number of bootstrap samples for estimating uncertainty. Set to zero to derive uncertainty from curvature of a single fit
minNRecInDayWindow	Minimum number of data points for regression
isAssociateParmsToMeanOfValids	set to FALSE to associate parameters to the first record of the window for interpolation instead of mean across valid records inside a window
isLasslopPriorsApplied	set to TRUE to apply strong fixed priors on LRC fitting. Returned parameter estimates claimed valid for some case where not enough data was available
isSdPredComputed	set to FALSE to avoid computing standard errors of Reco and GPP for small performance increase
isFilterMeteoQualityFlag	set to TRUE to use only records where quality flag of meteo drivers (Radation, Temperatrue, VPD) is zero, i.e. non-gapfilled for parameter estimation. For prediction, the gap-filled value is used always, to produce predictions also for gaps.
isBoundLowerNEEUncertainty	set to FALSE to avoid adjustment of very low uncertainties before day-Time fitting that avoids the high leverage those records with unreasonable low uncertainty.
smoothTempSensEstimateAcrossTime	set to FALSE to use independent estimates of temperature sensitivity on each windows instead of a vector of E0 that is smoothed over time

Value
