Description

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 calculations 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.
