aq_response: Non-rectangular hyperbolic model of light responses

In photosynthesis: Tools for Plant Ecophysiology & Modeling

Non-rectangular hyperbolic model of light responses

Description

Please use marshall_biscoe_1980().

Usage

aq_response(k_sat, phi_J, Q_abs, theta_J)

Arguments

k_sat	Light saturated rate of process k
phi_J	Quantum efficiency of process k
Q_abs	Absorbed light intensity (umol m-2 s-1)
theta_J	Curvature of the light response

Value

aq_response is used to describe the response of a process to absorbed light intensity. Assumes that input is absorbed light. Note that if absorbed light is not used, then the meaning of phi_J becomes unclear. This function is designed to be used with fit_aq_response, however it could easily be fed into a different fitting approach (e.g. Bayesian approaches). Originally from Marshall et al. 1980.
