MOD17A2_055

MODIS/Terra Gross Primary Productivity 8-Day L4 Global 1km SIN Grid V055

Version 055
  • 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. For further details regarding the differences between the NTSG and NASA versions of this product, please consult the document referenced in the following news release: https://lpdaac.usgs.gov/about/news_archive/terra_modis_gppnpp_products_ntsguniversity_montana 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.
