MODIS Net Primary Production CONUS (UMT/NTSG/v2/MODIS/NPP)
Version 0.2.0
The MODIS Net Primary Production (NPP) CONUS dataset estimates NPP using
MODIS Surface Reflectance for CONUS. NPP is the amount of
carbon captured by plants in an ecosystem, after accounting for losses due to
respiration. NPP is calculated using the MOD17 algorithm (see MOD17 User
Guide) with
MODIS Surface Reflectance, gridMET, and the National Land Cover Database.
