Summary
The Soil Adjusted and Atmospherically Resistant Vegetation Index (SARVI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 1992; its source is cited as Y.J. Kaufman, & D. Tanre (1992). Atmospherically resistant vegetation index (ARVI) for EOS-MODIS. IEEE Transactions on Geoscience and Remote Sensing, 30(2). https://doi.org/10.1109/36.134076 .
Based on the latest citation data, this index is in the 85.3th percentile overall, ranking 48 out of 313 indices with citation data. Among the 22 indices published within two years of 1992, it ranks 11 (59.09th percentile). Within the vegetation application domain, it is in the 80.57th percentile and ranks 43 out of 211 indices with citation data. Among the 22 similarly aged vegetation indices, it ranks 11 (59.09th percentile).
