El producto MOD17A3HGF V6.1 proporciona información sobre la productividad primaria bruta y neta (PPB y PPN) anuales con una resolución de píxeles de 500 m. El NPP anual se deriva de la suma de todos los productos de fotosíntesis neta(PSN) de 8 días (MOD17A2H) del año determinado. El valor de PSN es la diferencia entre la productividad primaria bruta (PPB) y la respiración de mantenimiento (RM) (PPB-RM).
