Landsat Surface Reflectance and Normalized Burn Ratio 2

This image displays a (left) Landsat 8 Surface Reflectance (SR) and (right) the SR-derived Landsat Surface Reflectance Normalized Burn Ratio 2 (NBR2).

Landsat Surface Reflectance-derived Landsat Normalized Burn Ration 2 (NBR2) are derived from Landsat 4–5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 8 Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS) scenes that can be successfully processed to Landsat Level-2 Surface Reflectance products.  

NBR2 modifies the Normalized Burn Ratio (NBR) to highlight water sensitivity in vegetation and may be useful in post-fire recovery studies. NBR2 is calculated as a ratio between the SWIR values, substituting the SWIR1 band for the NIR band used in NBR.

(SWIR1 – SWIR2) / (SWIR1 + SWIR2)

In Landsat 4-7, NBR2 = (Band 5 – Band 7) / (Band 5 + Band 7)

In Landsat 8, NBR2 = (Band 6 – Band 7) / (Band 6 + Band 7)

NBR2 isdelivered as a single band product, specified as shown in the table below.
