FIGURE 2.

Comparison of FvCB (solid black line) and CBGB (dashed black line) calculated carbon assimilation (A, μmol m⁻² s⁻¹) in response to C _a (left column) and I (right column) for the models, (a) and (e) in their original state and parameterization (Table 1), (b) and (f) in their original state but with common parameterization (using FvCB parameters Table 1). (c and g) FvCB and (d and h) CBGB showing the two or three potentially limiting rates A _c,g (green), A _j,g (blue) and A _p,g (purple) in addition to A (black solid or dashed). Vertical grey lines show the transition points between limiting rates for the FvCB (solid) and CBGB (dashed) models. Common parameterizations are for shared parameters, i.e. the quadratic smoothing parameters are not common as quadratic smoothing is not considered by FvCB even though selection of the minimum can be represented by a special case of quadratic smoothing
