Summary
The Carotenoid-Chlorophyll Ratio Index (CCRI) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 2019; its source is cited as Xianfeng Zhou, Wenjiang Huang, Jingcheng Zhang, Weiping Kong, Raffaele Casa, & Yanbo Huang (2019). A novel combined spectral index for estimating the ratio of carotenoid to chlorophyll content to monitor crop physiological and phenological status. International Journal of Applied Earth Observation and Geoinformation, 76. https://doi.org/10.1016/j.jag.2018.10.012 .
Based on the latest citation data, this index is in the 13.1th percentile overall, ranking 273 out of 313 indices with citation data. Among the 68 indices published within two years of 2019, it ranks 60 (13.24th percentile). Within the vegetation application domain, it is in the 12.32th percentile and ranks 186 out of 211 indices with citation data. Among the 34 similarly aged vegetation indices, it ranks 29 (17.65th percentile).
