We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.Read about the Web Unification Project

Description
The MOD17A3H Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the MOD17A3HGF Version 6.1 data product.
The MOD17A3H Version 6 product provides information about annual Net Primary Production (NPP) at 500 meter (m) pixel resolution. Annual NPP is derived from the sum of all 8-day Net Photosynthesis (PSN) products (MOD17A2H) from the given year. The PSN value is the difference of the Gross Primary Productivity (GPP) and the Maintenance Respiration (MR).
Known Issues
Forward processing of MOD17A3H Version 6 data product was discontinued on January 3, 2004, due to unexpected errors in the input data. Users are encouraged to use the MOD17A3HGF Version 6.1 data product.
The following changes and improvements were implemented for inputs to MODIS Version 6 gross primary productivity data products: (1) The product uses updated Biome Property look-up tables (BPLUT) and an updated version of the daily Global Modeling and Assimilation Office (GMAO) meteorological data, and (2) The products are now generated at the native resolution of 500 m using the Moderate Resolution Imaging Spectroradiometer (MODIS) Leaf Area Index(LAI)/Fraction of Photosynthetically Active Radiation (FPAR) (MOD15A2H) 8-day composite at 500 m resolution.
