Global satellite-derived data provides yearly composites of Gross and Net Primary Productivity (GPP/NPP) at a 500-meter spatial resolution. The dataset uses a gap-filling algorithm based on quality-controlled Leaf Area Index and Fraction of Photosynthetically Active Radiation inputs, improving upon previous versions. It is designed as a Level 4 product for modeling terrestrial energy, carbon, and water cycle processes.
Users cannot access this data in near-real-time; it is produced annually. Known issues are documented on a separate NASA/VIIRS Land Quality Assessment website.
