WebDescription. Atmospheric influence corrected surface reflectances of up to 7 spectral bands of reflectance measurements of the MODIS sensors aboard both EOS platforms: TERRA and AQUA, are used to derive the Leaf Area Index (LAI) and the fraction of the absorbed (by green vegetation) photosynthetically active, i.e. 400-700 nm, radiation (FAPAR). WebIt was concluded by previous researchers that MODIS MOD15A2H products give the overestimation or underestimation of LAI. From the Choudhury's method [1] of view, using the available MODIS products like vegetation indices, view zenith angle, sun azimuthal angle information LAI estimation can be improved.
