FvCB

The FvCB model (Farquhar, von Caemmerer & Berry, 1980) is a widely used framework for C3 photosynthesis. It describes net carbon assimilation An as the minimum of three potential rates — the RuBisCO-limited rate Wc, the electron-transport-limited rate Wj, and the triose-phosphate-utilisation-limited rate Wp — evaluated across a range of intercellular CO₂ (Ci).

  W_p &= \begin{cases}100 & C_i \leq \Gamma^* \cdot (1 + 3 \cdot \alpha) \\ \frac{3 \cdot C_i \cdot T_p}{C_i - \Gamma^* \cdot (1 + 3 \cdot \alpha)} & \text{else}\end{cases} \\
