1 Introduction Terrestrial gross primary production (GPP) is the flux of carbon into the land surface driven by photosynthesis. It is estimated that terrestrial GPP is in the order of ∼132 PgC and is the single largest annual flux of the global carbon cycle. It plays a key role in determining atmospheric carbon dioxide, since approximately a quarter to a third of anthropogenic emissions are sequestered by the land surface (Canadell et al., 2021; Schimel et al., 2001; Schwalm et al., 2020).
