A two‐leaf rectangular hyperbolic model for estimating GPP across vegetation types and climate conditions

Abstract There are mainly three types of gross primary production (GPP), including light use efficiency (LUE) model, rectangular hyperbolic model (RHM), and process‐based model (PBM). RHM is not widely used because its parameters, namely, quantum yield ( α ) and maximum photosynthetic rate (P m ), vary temporally with temperature and spatially with vegetation type under natural conditions. In the study, we present a temperature‐ and …
