The Landsat Gross Primary Production (GPP) CONUS dataset estimates GPP using
Landsat Surface Reflectance for CONUS. GPP is the amount of
carbon captured by plants in an ecosystem and is an essential component in
the calculations of Net Primary Production (NPP). GPP is calculated using the
MOD17 algorithm (see MOD17 User
Guide) with
Landsat Surface Reflectance, gridMET, and the National Land Cover Database.
