Summary
The Carotenoid Index (CARI) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 2017; its source is cited as Xianfeng Zhou, Wenjiang Huang, Weiping Kong, Huichun Ye, Yingying Dong, & Raffaele Casa (2017). Assessment of leaf carotenoids content with a new carotenoid index: Development and validation on experimental and model data. International Journal of Applied Earth Observation and Geoinformation, 57. https://doi.org/10.1016/j.jag.2016.12.005 .
