Seasonal and inter-annual variability of photosynthetic capacity in a temperate forest

In temperate forests, the relation between vegetation phenology and carbon sequestration variability remains to be explored. To study phenology impact on CO2 fluxes, two photosynthetic
capacity indicators were used : NEE at light saturation (NEEsat) and green proportion in canopy pictures (gcc). Correlations between these indicators were investigated at seasonal and inter-annual scale.
