VegetationMultispectralCitation Rank #24

Summary

The Simple Ratio (SR) is a vegetation spectral index intended for multispectral sensing. It was introduced in 1969; its source is cited as Carl F. Jordan (1969). Derivation of Leaf‐Area Index from Quality of Light on the Forest Floor. Ecology, 50(4). https://doi.org/10.2307/1936256 .

Based on the latest citation data, this index is in the 92.65th percentile overall, ranking 24 out of 313 indices with citation data. Among the 2 indices published within two years of 1969, it ranks 1 (100th percentile). Within the vegetation application domain, it is in the 90.52th percentile and ranks 21 out of 211 indices with citation data. Among the 2 similarly aged vegetation indices, it ranks 1 (100th percentile).
