The MOD17A3H Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the [MOD17A3HGF Version 6.1](https://doi.org/10.5067/MODIS/MOD17A3HGF.061) 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](https://doi.org/10.5067/MODIS/MOD17A2H.006)) 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](https://doi.org/10.5067/MODIS/MOD17A3HGF.061) data product.* For complete information about known issues please refer to the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=MODIS&sat=Terra&as=6).Improvements/Changes from Previous Versions* 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.* 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](https://doi.org/10.5067/modis/mod15a2h.006)) 8-day composite at 500 m resolution.
