Summary
The Modified Photochemical Reflectance Index 4 (PRIm4) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 2011; its source is cited as RocĂo Hernández-Clemente, Rafael M. Navarro-Cerrillo, Lola Suárez, FermĂn Morales, & Pablo J. Zarco-Tejada (2011). Assessing structural effects on PRI for stress detection in conifer forests. Remote Sensing of Environment, 115(9). https://doi.org/10.1016/j.rse.2011.04.036 .
Based on the latest citation data, this index is in the 47.28th percentile overall, ranking 167 out of 313 indices with citation data. Among the 26 indices published within two years of 2011, it ranks 13 (57.69th percentile). Within the vegetation application domain, it is in the 33.65th percentile and ranks 142 out of 211 indices with citation data. Among the 8 similarly aged vegetation indices, it ranks 5 (62.5th percentile).
