PIPlatt

Function

$y = P_{m}\cdot tanh\left (\frac {\alpha\cdot x}{P_{m}}\right )$

Model of photosynthesis vs. irradiance curve by Platt.

Number: 2

Names: Pm, alpha

Meanings: Pm = photosynthetic capacity, alpha = photosynthetic efficiency

Lower Bounds: Pm > 0, alpha > 0

Upper Bounds: none

Refer to the curve in Sample Curve section:

Half-saturation constant: Ik = atanh(0.5)*Pm/alpha
