The MCD15A3H V6 level 4, Combined Fraction of Photosynthetically
Active Radiation (FPAR), and Leaf Area Index (LAI) product is a
4-day composite data set with 500 meter pixel size. The algorithm
chooses the "best" pixel available from all the acquisitions of
both MODIS sensors located on NASA's Terra and Aqua satellites
from within the 4-day period.
