MOD17A2_005

MODIS/Terra Gross Primary Productivity 8-Day L4 Global 1km SIN Grid V005

Version 005
  • Abstract
    The Terra/MODIS Gross Primary Productivity (GPP) product (MOD17A2) is a cumulative composite of GPP values based on the radiation-use efficiency concept that is potentially used as inputs to data models to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. MOD17A2 is an 8-day composite at 1-km spatial resolution delivered as a gridded level-4 product in Sinusoidal projection. The MODIS Adaptive Processing System (MODAPS) at the Goddard Spaceflight Center produces this GPP product. Users are encouraged to use the Numerical Terradynamic Simulation Group (NTSG)/University of Montana’s (UMT) version of this product available as version-55 from the LP DAAC. For more information, refer to the product details via the “Version 055” tab. Version-5 and Version-55 Terra/MODIS GPP products are validated to Stage-3; this means that its accuracy was assessed and uncertainties in the product were well-established via independent measurements made in a systematic and statistically robust way that represents global conditions. These data are deemed ready for use in science applications.
