Summary
The Optimized Pigment Specific Normalized Difference for Chlorophyll b (OPSNDb) is a vegetation spectral index intended for hyperspectral sensing. It was introduced in 1998; its source is cited as G. A. Blackburn (1998). Spectral indices for estimating photosynthetic pigment concentrations: A test using senescent tree leaves. International Journal of Remote Sensing, 19(4). https://doi.org/10.1080/014311698215919 .
Based on the latest citation data, this index is in the 70.93th percentile overall, ranking 93 out of 313 indices with citation data. Among the 41 indices published within two years of 1998, it ranks 13 (73.17th percentile). Within the vegetation application domain, it is in the 61.61th percentile and ranks 83 out of 211 indices with citation data. Among the 36 similarly aged vegetation indices, it ranks 12 (72.22th percentile).
