It incorporates an “L” value to adjust for canopy background, “C” values as coefficients for atmospheric resistance, and values from the blue band (B). These enhancements allow for index calculation as a ratio between the R and NIR values, while reducing the background noise, atmospheric noise, and saturation in most cases.

The image is applied with a divergent blue-green to brown color palette. It depicts areas with a lot of green leaf growth, indicating the presence of chlorophyll, in dark green colors.Chlorophyll reflects more infrared light and less visible light. Areas with some green leaf growth are in light yellows, and areas with little to no vegetation growth are in shades of brown.

The Reflectance imagery layer from Sentinel-2A and Sentinel-2B/MSI product (S30) is available through the HLS project from the Multi-Spectral Instrument (MSI) aboard the European Union’s Copernicus Sentinel-2A and Sentinel-2B satellites. The sensor resolution is 10, 20, and 60 m, imagery resolution is resampled to 30 m, and the temporal resolution is daily with a 5 day revisit time. The imagery is available in Worldview/GIBS approximately 2 - 4 days after satellite overpass. There is a separate combined Landsat 8 and 9 imagery layer available.

The dynamically generated Normalized Difference Water Index (NDWI) (B3-B5)/(B3+B5) imagery layer is useful for identifying water bodies and to monitor changes related to water content in water bodies. It is calculated using green and near infrared wavelengths.

It is calcuated using:

The dynamically generated Soil Adjusted Vegetation Index (SAVI) imagery layer is used to correct Normalized Difference Vegetation Index (NDVI) for the influence of soil brightness in areas where vegetative cover is low. Surface Reflectance-derived SAVI is calculated as a ratio between the R and NIR values with a soil brightness correction factor (L) defined as 0.5 to accommodate most land cover types.

It is calcuated using:
It is calculated using:

`SAVI = ((NIR - R) / (NIR + R + L)) * (1 + L)`

Specifically for Landsat 8 and 9:

`SAVI = ((Band 5 – Band 4) / (Band 5 + Band 4 + 0.5)) * (1.5)`
