annual Net Primary Productivity (NPP) at 500m pixel resolution.
Annual NPP is derived from the sum of the 45 8-day Net Photosynthesis
(PSN) products (MOD17A2H) from the given year. The PSN value
is the difference of the GPP and the Maintenance Respiration
(MR) (GPP-MR).
This is a NASA version of this product. Another
version is produced by the Numerical Terradynamic Simulation
Group (NTSG), University of Montana
(UMT). The NTSG version corrects the problem with cloud-contaminated
MODIS LAI-FPAR inputs to the MOD17 algorithm, but its resolution
is 1km. It is ingested into Earth Engine as MODIS/055/MOD17A3.
For further details regarding the differences between the NTSG
and NASA versions of this product, please consult this document
