MODIS/Terra Gap-Filled, Smoothed LAI-FPAR 8-Day L4 Global 1km SIN Grid
The MODIS/Terra Gap-Filled, Smoothed Leaf Area Index (LAI) and Fraction of Photosynthetically Active Radiation (FPAR) 8-Day L4 Global 1km SIN Grid product with short-name MOD15A2GFS, is composited every 8 days at 1-kilometer resolution on a Sinusoidal grid. 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.
