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\nLandsat Surface Reflectance, gridMET, and the National Land Cover Database.\n\n### Bands\n\n\n**Pixel Size**\n\n30 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 production |\n| `QC` | % | 0 | 255 | | meters | Percentage of gap-filled Landsat 16-day composites.
