Assessment of vegetation indices for regional crop green LAI estimation from Landsat images over multiple growing seasons

► Assessed a few vegetation indices for estimating LAI using Landsat data. ► Performed global sensitivity analysis of vegetation indices to interference factors. ► Indices are affected differently by the interference factors. ► Wider bandwidth degraded MTVI2 performance in reducing chlorophyll and soil effects. ► Need to be aware of the variability of interference factors in using LAI products.
