NEESdVar

Variable of standard deviation of net ecosystem fluxes

TempVar

Filled air or soil temperature variable (degC)

QFTempVar

Details

The LRC fit usually weights NEE records by its uncertainty. In order to also use records with missing NEESdVar, uncertainty of the missing values is by default set to a conservatively high value, parameterized by controlGLPart$replaceMissingSdNEEParms). Controlled by argument replaceMissingSdNEEParms in partGLControl, but overruled by argument neglectNEEUncertaintyOnMissing.

Value

a data.frame with columns

sDateTime

first column of ds, usually the time stamp not used, but usually first column is a DateTime is kept for aiding debug

NEE

NEE filtered for quality flay

sdNEE

standard deviation of NEE with missing values replaced

Temp

Temperature, quality filtered if isTRUE(controlGLPart$isFilterMeteoQualityFlag)

VPD

Water pressure deficit, quality filtered if isTRUE(controlGLPart$isFilterMeteoQualityFlag)

Rg

Incoming radiation

isDay

Flag that is true for daytime records

isNight

Flag that is true for nighttime records
