energy.use.efficiency {bigleaf}

Energy-Use Efficiency (EUE)

Description

Fraction of net radiation fixed by primary productivity.

Usage

energy.use.efficiency(GPP, alpha = 0.422, Rn)

Arguments

GPP

Gross primary productivity exchange (umol CO2 m-2 s-1)

alpha

Energy taken up/released by photosynthesis/respiration (J umol-1)

Rn

Net radiation (W m-2)

Details

Energy use efficiency is calculated as:

EUE = sum(GPP)/sum(Rn)

where the sums are calculated for complete cases of GPP and Rn over the entire time period.

Value

EUE -

Energy use efficiency (-)
