PSRIPlant Senescence Reflectance Index

VegetationHyperspectralCitation Rank #49

Summary

The Plant Senescence Reflectance Index (PSRI) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 1999; its source is cited as Mark N. Merzlyak, Anatoly A. Gitelson, Olga B. Chivkunova, & Victor YU. Rakitin (1999). Non‐destructive optical detection of pigment changes during leaf senescence and fruit ripening. Physiologia Plantarum, 106(1). https://doi.org/10.1034/j.1399-3054.1999.106119.x .

Based on the latest citation data, this index is in the 84.66th percentile overall, ranking 49 out of 313 indices with citation data. Among the 43 indices published within two years of 1999, it ranks 4 (93.02th percentile). Within the vegetation application domain, it is in the 79.62th percentile and ranks 44 out of 211 indices with citation data. Among the 36 similarly aged vegetation indices, it ranks 4 (91.67th percentile).
