Canopy chlorophyll content index
WebResults indicated that canopy chlorophyll content can be remotely evaluated by VIs with r 2 ranging from the lowest of 0.73 for NDVI to the highest of 0.86 for CI green. EVI had a greater precision (r 2 =0.81) than MASVI (r 2 =0.75) in canopy chlorophyll content estimation. The results agreed well with the sensitivity study and will be helpful ... WebApr 3, 2010 · One spectral index, the canopy chlorophyll content index (CCCI) designed to detect canopy N using three wavebands along the “red edge” of the spectrum was combined with the canopy nitrogen index (CNI), which was developed to normalize for crop biomass and correct for the N dilution effect of crop canopies.
