MODIS/Aqua Leaf Area Index/FPAR 8-Day L4 Global 1km SIN Grid V005

Version 005
  • Abstract
    The level-4 MODIS global Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) product is composited every 8 days at 1-kilometer resolution on a Sinusoidal grid. Science Data Sets provided in the MYD15A2 include LAI, FPAR, a quality rating, and standard deviation for each variable. The LAI variable defines the number of equivalent layers of leaves relative to a unit of ground area, whereas FPAR measures the proportion of available radiation in the photosynthetically active wavelengths that are absorbed by a canopy. Both variables are used as satellite-derived parameters for calculating surface photosynthesis, evapotranspiration, and net primary production, which in turn are used to calculate terrestrial energy, carbon, water cycle processes, and biogeochemistry of vegetation. V005 Data Set Characteristics: Area: ~10 x 10 km Size: 1200 x 1200 rows/columns File Size: ~0.2 MB compressed Resolution: 1000 meters Projection: Sinusoidal Data Format: HDF-EOS Science Data Sets (SDS HDF Layers):6
