WebOverview. The Primary Production products are designed to provide an accurate regular measure of the growth of the terrestrial vegetation. Production is determined by first computing a daily net photosynthesis value which is then composited over an 8-day interval of observations for a year. The product is a cumulative composite of GPP values ... WebWelcome to the NPP Products path.
