NPP is the amount of\ncarbon captured by plants in an ecosystem, after accounting for losses due to\nrespiration. NPP is calculated using the MOD17 algorithm (see [MOD17 User\nGuide](https://www.ntsg.umt.edu/files/modis/MOD17UsersGuide2015_v3.pdf)) with\nMODIS Surface Reflectance, gridMET, and the National Land Cover Database.\n\n### Bands\n\n\n**Pixel Size**\n\n250 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Scale | Pixel Size | Description |\n|-------------|------------|-----|-------|--------|------------|---------------------------------------|\n| `annualNPP` | kg\\*C/m\\^2 | 0 | 65535 | 0.0001 | meters | Annual net primary productivity |\n| `QC` | % | 0 | 100 | | meters | Percentage of gap-filled NDVI values. |\n\n### Terms of Use\n\n**Terms of Use**\n\nThis work is in the public domain and is free of known copyright\nrestrictions.
