Summary
The Snow Water Index (SWI) is a snow spectral index intended for multispectral sensing. It was introduced in 2019; its source is cited as Abhilasha Dixit, Ajanta Goswami, & Sanjay Jain (2019). Development and Evaluation of a New “Snow Water Index (SWI)” for Accurate Snow Cover Delineation. Remote Sensing, 11(23). https://doi.org/10.3390/rs11232774 .
Based on the latest citation data, this index is in the 15.77th percentile overall, ranking 268 out of 317 indices with citation data. Among the 70 indices published within two years of 2019, it ranks 58 (18.57th percentile). Within the snow application domain, it is in the 40th percentile and ranks 7 out of 10 indices with citation data. Among the 3 similarly aged snow indices, it ranks 2 (66.67th percentile).
