aq_response function

Non-rectangular hyperbolic model of light responses

Please use marshall_biscoe_1980().

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

Returns

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.
