NOAA-20 VIIRS VJ117A2 Version 2 is a Level 4 gridded data product providing cumulative composites of Gross Primary Productivity (GPP) and Net Photosynthesis (PSN) for terrestrial vegetation. The dataset is based on the radiation use efficiency concept and is delivered as an 8-day composite at a 500-meter spatial resolution in a Sinusoidal projection. It includes layers for GPP, PSN, and a quality control layer, serving as inputs for modeling terrestrial energy, carbon, and water cycle processes.
