⚠️There's a newer version (1.2.3) of this package.Take me there.

rpmodel (version 1.2.0)

P-Model

Description

Implements the P-model (Stocker et al., 2020 ), predicting acclimated parameters of the enzyme kinetics of C3 photosynthesis, assimilation, and dark respiration rates as a function of the environment (temperature, CO2, vapour pressure deficit, light, atmospheric pressure).
