Relations between NDVI and FAI (foliage area index) and fAPAR (fraction of absorbed photosynthetically active radiation) are examined using simulated MISR data. More linear, statistically significant relationships between FAI (fAPAR) and shaded (sunlit) foliage fraction are identified. The dominant role of the sunlit scene component in determining scene NDVI is physically interpreted, and a more effective (accurate) way to use NDVI (to estimate FAI and fAPAR) is also suggested
