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 13.25th percentile overall, ranking 276 out of 317 indices with citation data. Among the 70 indices published within two years of 2019, it ranks 62 (12.86th percentile). Within the vegetation application domain, it is in the 12.21th percentile and ranks 188 out of 213 indices with citation data. Among the 36 similarly aged vegetation indices, it ranks 31 (16.67th percentile).
