Fig. 2: Distribution of leaf scale gross primary production (GPPL) trends in different intervals of growing season average leaf area index (LAI).

Fig. 2

a GPPL trends in simulations with time-varying CO2 concentration, climate and fraction of vegetation-absorbed photosynthetically active radiation (FPAR) during 2001–2021 period. b GPPL trends due only to the CO2 fertilization effect (CFE). c GPPL trends due only to time-varying climate. d GPPL trends due only to time-varying FPAR. The simulations with production efficiency models (PEMs) are described in Methods §11. The growing season is defined as the period when daily GPPC > 0 and daily LAI > 0.1.
