Summary
The Ratio Analysis of Reflectance Spectra for Chlorophyll a (RARSa) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 1992; its source is cited as Emmett W Chappelle, Moon S Kim, & James E McMurtrey (1992). Ratio analysis of reflectance spectra (RARS): An algorithm for the remote estimation of the concentrations of chlorophyll A, chlorophyll B, and carotenoids in soybean leaves. Remote Sensing of Environment, 39(3). https://doi.org/10.1016/0034-4257(92)90089-3 .
Based on the latest citation data, this index is in the 73.8th percentile overall, ranking 83 out of 313 indices with citation data.
