Landsat Normalized Burn Ratio 2
Normalized Burn Ratio 2 (NBR2) modifies the Normalized Burn Ratio (NBR) to highlight water sensitivity in vegetation and may be useful in post-fire recovery studies.
Return to Landsat Surface Reflectance-derived Spectral Indices Overview
Landsat Surface Reflectance-derived Landsat Normalized Burn Ration 2 (NBR2) are acquired from Landsat 4–5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and Landsat 8-9* Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS) Collection 1 and Collection 2 scenes that have been processed to Landsat Level-2 Surface Reflectance products. *Landsat 9 = Collection 2 only
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 8-9, NBR2 = (Band 6 – Band 7) / (Band 6 + Band 7)
NBR2 is delivered as a single band product, specified as shown in the table below.
