Sentinel-2 Brightness Index (BI)

This index results from the following equation: Brightness Index = sqrt( (Red^2 / Green^2) /2) using Sentinel-2 Bands 4 (Red) and 3 (Green). The index is sensitive to the brightness of soils. High soil brightness is linked with soil humidity and the presence of salts in the soil. The Brightness Index is labeled S2_BI in the Food Security TEP.
