eCanA(LAI, doy, hour, solarR, AirTemp, RH, WindS, Vcmax, 
    Vpmax, Vpr, Jmax, Ca = 380, Oa = 210, StomataWS = 1)

Arguments

LAI

leaf area index.

doy

day of the year, (1–365).

hour

hour of the day, (0–23).

solarR

solar radiation (micro mol /m2/s).

AirTemp

temperature (Celsius).

RH

relative humidity (0–1).

WindS

wind speed (m/s).

Vcmax

Maximum rubisco activity (micro mol /m2/s).

Vpmax

Maximum PEP carboxylase activity (micro mol /m2/s).

Vpr

PEP regeneration rate (micro mol /m2/s).

Jmax

Maximal electron transport rate (micromol electrons m-2 s-1).

Ca

atmospheric carbon dioxide concentration (ppm or microbar) (e.g. 380).

Oa

atmospheric oxygen concentration (mbar) (e.g. 210).

StomataWS

Effect of water stress on assimilation.

Value

numeric

returns a single value which is hourly canopy assimilation (mol m-2 ground s-1)
