f.modified.arrhenius.inv: Temperature dependence of Jmax and Vcmax

In TESTgroup-BNL/LeafGasExchange: A package containing functions for fitting photosynthetic response curves, simulat leaf and canopy photosynthesis

Temperature dependence of Jmax and Vcmax

Description

Retrieve the reference temperature value of a parameter knowing its value at Tleaf

Usage

f.modified.arrhenius.inv(P, Ha, Hd, s, Tleaf, TRef = 298.16, R = 8.314)

Arguments

P	Value of the parameter, here Vcmax or Jmax, at the leaf temperature in micromol.m-2.s-1
Ha	Energy of activation in J.mol-1.
Hd	Energy of desactivation in J.mol-1.
s	Entropy term in J.mol-1.K-1.
Tleaf	Temperature of the leaf in Kelvin.
TRef	Reference temperature in Kelvin, usually 25 + 273.16 K.
R	Ideal gas constant.

Value

Value of the parameter Jmax or Vcmax at the reference temperature

Examples

VcmaxTleaf=f.modified.arrhenius(PRef=50,Ha=73637,Hd=149252,s=486,Tleaf=seq(273.15+25,273.15+35,0.1))
f.modified.arrhenius.inv(P=VcmaxTleaf,Ha=73637,Hd=149252,s=486,Tleaf=seq(273.15+25,273.15+35,0.1))
