eCanA: Simulates canopy assimilation (von Caemmerer model)

In BioCro: Simulation of Biomass Crops

Description

It represents an integration of the photosynthesis function eC4photo, canopy evapo/transpiration and the multilayer canopy model sunML.

Usage

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)
