FDIFloating Debris Index

WaterMultispectralCitation Rank #157

Summary

The Floating Debris Index (FDI) is a water spectral index intended for multispectral sensing. It was introduced in 2020; its source is cited as Lauren Biermann, Daniel Clewley, Victor Martinez-Vicente, & Konstantinos Topouzelis (2020). Finding Plastic Patches in Coastal Waters using Optical Satellite Data. Scientific Reports, 10(1). https://doi.org/10.1038/s41598-020-62298-z .

Based on the latest citation data, this index is in the 50.16th percentile overall, ranking 157 out of 313 indices with citation data. Among the 73 indices published within two years of 2020, it ranks 7 (91.78th percentile). Within the water application domain, it is in the 67.74th percentile and ranks 11 out of 31 indices with citation data. Among the 13 similarly aged water indices, it ranks 1 (100th percentile).
