AfSIS MODIS Collection: Primary Productivity, 2012 Release

The Africa Soil Information Service (AfSIS) Moderate Resolution Imaging Spectroradiometer (MODIS) Collection's Primary Productivity data set contains rasters with the following calculations: time series average, time series variance, and annual averages for Net Primary Productivity (NPP) and Gross Primary Productivity (GPP). These Africa continent-wide calculations for vegetation productivity use observations from the National Aeronautics and Space Administration (NASA) MODIS MOD17A3 product. The rasters have a annual temporal resolution, a spatial resolution of 1 kilometer, and are updated annually by AfSIS using data provided by the U.S. Geological Survey (USGS) Land Processes Distributed Active Archive Center (LPDAAC) Data Pool at https://lpdaac.usgs.gov. The data are available in Geographic Tagged Image File Format (GeoTIFF) from the Africa Soil Information Service (AfSIS).
