MODIS Gross Primary Production CONUS (UMT/NTSG/v2/MODIS/GPP)
Version 0.2.0
The MODIS Gross Primary Production (GPP) CONUS dataset estimates GPP using
MODIS Surface Reflectance for CONUS. GPP is the amount of
carbon captured by plants in an ecosystem and is an essential component in
the caculations of Net Primary Production (NPP). GPP is calculated using the
MOD17 algorithm (see MOD17 User
Guide) with
MODIS Surface Reflectance, gridMET, and the National Land Cover Database.
| Name | Description | Gee:unit | Gee:scale |
|---|---|---|---|
| GPP | 8-day gross primary production | kg*C/m^2/8-day | 0.0001 |
| QC | Indicates if the original NDVI value was adjusted through the smoothing algorithm. 0 denotes the value was not adjusted. 1 indicates the value was adjusted. |
