Defined as the net amount of biomass, or carbon, produced by plants per unit area and time, expressed in gC/m²/day. It is equal to the difference between the Gross Primary Production (GPP), i.e. the total amount of carbon produced through photosynthesis, and the amount of energy used for plant respiration. Every 10-days estimates are available in near real time at global scale in the spatial resolution of about 300 m from January 2014 to the present.
