“…Moreover, several authors [76][77][78] highlight that although NDVI is commonly used to retrieve LAI values, it is not always the VI with the highest correlation. In particular, for S-2, the newest of the three satellites, alternative Vis may be considered to improve results [32,[79][80][81].…”

“…Satellite remote sensing in comparison with other platforms has the advantage of offering readily available, sometimes free of charge, reflectance data over large areas. Satellites can also support monitoring programs through time spans of several years, ensuring long term information continuity through global LAI products (Defourny et al, 2019;Fang et al, 2019;Sinha et al, 2020). Most available global LAI products such as "LAI 300 m", "LAI 1 km" (both from Copernicus Global Land Service), and "MODIS Leaf Area Index" (NASA), however, cannot offer LAI estimates at a spatial resolution higher than 300 m, which makes them unsuitable for precision agriculture.…”

“…Empirical regression models based on VIs are widely used due to their simplicity and robustness. A common practice is modeling from the field vegetation parameters (e.g., Cab or leaf area index) and the remote sensing data (e.g., VIs or reflectance) [18]. Most VIs are calculated from the visible, red-edge, and near-infrared spectral domains, such as the widely used normalized difference vegetation index (NDVI), modified chlorophyll absorption ratio index (MCARI), and the double-peak canopy nitrogen index (DCNI) [19].…”
