WebA strong linear relation also exists between MODIS fAPAR and NDVI but with different regression coefficients than the in situ relation because of MODIS' tendency to overestimate fAPAR. The fAPAR/NDVI relations found here, however, do not apply on a global scale but are only valid for similar sun-sensor view geometry and soil colour. Web3 de jun. de 2010 · The strong relationship between NDVI and fAPAR has been examined in detail through theoretical and experimental analyses [10,12,13]. The NDVI has become a popular tool for assessing different aspects of plant processes while simultaneously determining spatial variation in vegetation cover .
