VIIRS/NPP Gross Primary Productivity and Net Photosynthesis 8-Day L4 Global 500m SIN Grid V002

Published by LP DAAC;NASA/GSFC/SED/ESD/TISL/LandSIPS | National Aeronautics and Space Administration | Catalog Last Checked: August 18, 2026 at 11:32 PM | Dataset Last Updated: August 18, 2026
The NASA/NOAA Suomi National Polar-orbiting Partnership (Suomi NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Gross Primary Productivity (GPP) and Net Photosynthesis (PSN) (VNP17A2) Version 2 data product is a cumulative composite of GPP values based on the radiation use efficiency concept that is potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. VNP17A2 is an 8-day composite at 500 meter (m) spatial resolution delivered as a gridded Level 4 (L4) product in Sinusoidal projection. Provided in the VNP17A2 product are 3 variables for GPP, PSN, along with a quality control variable. A low resolution browse image for GPP is also available for each VNP17A2 granule. Known Issues * For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=VIIRS).
