Published by LP DAAC;NASA/GSFC/SED/ESD/TISL/MODAPS | National Aeronautics and Space Administration | Catalog Last Checked: July 14, 2026 at 10:17 PM | Dataset Last Updated: June 23, 2026
The MOD17A2H Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the [MOD17A2H Version 6.1](https://doi.org/10.5067/MODIS/MOD17A2H.061) data product. The MOD17A2H Version 6 Gross Primary Productivity (GPP) product is a cumulative 8-day composite of values with 500 meter (m) pixel size based on the radiation use efficiency concept that can be potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. The data product includes information about GPP and Net Photosynthesis (PSN). The PSN band values are the GPP less the Maintenance Respiration (MR). The data product also contains a PSN Quality Control (QC) layer. The quality layer contains quality information for both the GPP and the PSN.
