partGLEstimateTempSensInBoundsE0Only: partGLEstimateTempSensInBoundsE0Only

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

Description

Estimate temperature sensitivity E_0 and R_ref of ecosystem respiration, and apply bounds or previous estimate

Usage

partGLEstimateTempSensInBoundsE0Only(REco, temperatureKelvin, 
    prevE0 = NA)

Arguments

REco	numeric vector: night time NEE, i.e. ecosytem respiration
temperatureKelvin	numeric vector: temperature in Kelvin of same length as REco
prevE0	numeric scalar: the previous guess of Temperature Sensitivity

Details

Basal respiration is reported for temperature of 15 degree Celsius. However during the fit a reference temperature of the median of the dataset is used. This is done to avoid strong correlations between estimated parameters E0 and R_ref, that occure if reference temperature is outside the center of the data.

If E_0 is out of bounds [50,400] then report E0 as NA

Value

list with entries

E0	numeric scalar of estimated temperature sensitivty E0 bounded to [50,400]
sdE0	numeric scalar of standard deviation of E0
TRefFit	numeric scalar reference temperature used in the E0 fit
RRefFit	numeric scalar respiration at TRefFit
