energy.use.efficiency {bigleaf} | R Documentation |
Fraction of net radiation fixed by primary productivity.
energy.use.efficiency(GPP, alpha = 0.422, Rn)
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) |
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.
