Summary
The Atmospheric Resistant Green-Red Index (GRARI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 1996; its source is cited as Anatoly A. Gitelson, Yoram J. Kaufman, & Mark N. Merzlyak (1996). Use of a green channel in remote sensing of global vegetation from EOS-MODIS. Remote Sensing of Environment, 58(3). https://doi.org/10.1016/s0034-4257(96)00072-7 .
Based on the latest citation data, this index is in the 96.81th percentile overall, ranking 13 out of 313 indices with citation data. Among the 47 indices published within two years of 1996, it ranks 4 (97.87th percentile). Within the vegetation application domain, it is in the 96.21th percentile and ranks 11 out of 211 indices with citation data. Among the 43 similarly aged vegetation indices, it ranks 3 (100th percentile).
