Summary
The Physiological Reflectance Index at 570 nm (PRI570) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 1992; its source is cited as J.A. Gamon, J. Peñuelas, & C.B. Field (1992). A narrow-waveband spectral index that tracks diurnal changes in photosynthetic efficiency. Remote Sensing of Environment, 41(1). https://doi.org/10.1016/0034-4257(92)90059-s .
Based on the latest citation data, this index is in the 89.46th percentile overall, ranking 35 out of 313 indices with citation data. Among the 22 indices published within two years of 1992, it ranks 4 (90.91th percentile). Within the vegetation application domain, it is in the 86.73th percentile and ranks 30 out of 211 indices with citation data. Among the 22 similarly aged vegetation indices, it ranks 4 (90.91th percentile).
