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 50.79th percentile overall, ranking 157 out of 317 indices with citation data. Among the 76 indices published within two years of 2020, it ranks 7 (92.11th percentile). Within the water application domain, it is in the 68.75th percentile and ranks 11 out of 32 indices with citation data. Among the 14 similarly aged water indices, it ranks 1 (100th percentile).
