MOD 15 - Leaf Area Index (LAI) and Fractional Photosynthetically Active Radiation (FPAR)
Description:
MODIS FPAR/LAI is the Fraction of Absorbed Photosynthetically Active radiation that a plant canopy absorbs for photosynthesis and growth in the 0.4 – 0.7nm spectral range. FPAR is expressed as a unitless fraction of the incoming radiation received by the land surface. Leaf area index is the biomass equivalent of FPAR, and is also a dimensionless ratio (m2/m2) of leaf area covering a unit of ground area. Both of these variables are computed daily at 1km from MODIS spectral reflectances for all vegetated land surface globally. The MOD15 FPAR/LAI are essential inputs for the MOD16 Evapotranspira-tion, and MOD 17 vegetation gross primary production/net primary production data products.
