NMDINormalized Multi-band Drought Index

VegetationMultispectralCitation Rank #125

Summary

The Normalized Multi-band Drought Index (NMDI) is a vegetation spectral index intended for multispectral sensing. It was introduced in 2007; its source is cited as Lingli Wang, & John J. Qu (2007). NMDI: A normalized multi‐band drought index for monitoring soil and vegetation moisture with satellite remote sensing. Geophysical Research Letters, 34(20). https://doi.org/10.1029/2007gl031021 .

Based on the latest citation data, this index is in the 60.88th percentile overall, ranking 125 out of 317 indices with citation data. Among the 41 indices published within two years of 2007, it ranks 13 (70.73th percentile). Within the vegetation application domain, it is in the 47.89th percentile and ranks 112 out of 213 indices with citation data. Among the 23 similarly aged vegetation indices, it ranks 8 (69.57th percentile).
