  description: The Version 6.1 product provides information about annual Net Primary
    Production (NPP) at 500 meter (m) pixel resolution. Annual Moderate Resolution
    Imaging Spectroradiometer (MODIS) NPP is derived from the sum of all 8-day Net
    Photosynthesis (PSN) products (MOD17A2H) from the given year. The PSN value is
    the difference of the Gross Primary Productivity (GPP) and the Maintenance Respiration
    (MR). The product will be generated at the end of each year when the entire yearly
    8-day 15A2H is available. Hence, the gap-filled product is the improved 17, which
    has cleaned the poor-quality inputs from 8-day Leaf Area Index and Fraction of
    Photosynthetically Active Radiation (LAI/FPAR) based on the Quality Control (QC)
    label for every pixel. If any LAI/FPAR pixel did not meet the quality screening
    criteria, its value is determined through linear interpolation. However, users
    cannot get this product in near-real time because it will be generated only at
    the end of a given year.
