Parameters that specify a flat temperature response (in other words, no
dependence on temperature) for important C4 photosynthetic parameters,
intended to be passed to the calculate_temperature_response
function.
c4_temperature_param_flatList with 10 named elements that each represent a variable whose temperature-dependent value can be calculated using either an Arrhenius or Gaussian equation:
Vcmax_norm: The maximum rate of rubisco carboxylation
(Vcmax) normalized to its value at 25 degrees C.
Vpmax_norm: The maximum rate of PEP carboxylase activity
(Vpmax) normalized to its value at 25 degrees C.
RL_norm: The respiration rate (RL) normalized to the
value of Vcmax at 25 degrees C.
Kc: The Michaelis-Menten constant for rubisco carboxylation.
Ko: The Michaelis-Menten constant for rubisco oxygenation.
Kp: The Michaelis-Menten constant of PEP carboxylase.
gamma_star: Half the reciprocal of rubisco specificity.
ao: The ratio of solubility and diffusivity of O2 to CO2.
gmc_norm: The mesophyll conductance to CO2 diffusion normalized
to its value at 25 degrees C.
J_norm: The electron transport rate J normalized to its
value at 25 degrees C.
Each of these is a list with 4 named elements:
type: the type of temperature response ('Arrhenius')
c: the (dimensionless) Arrhenius scaling factor.
Ea: the activation energy in kJ / mol.
units: the units of the corresponding variable.
