Summary<\/span><\/p>

This product shows burn severity computed from the Differenced Normalized Burn Ratio (dNBR) for each pixel. The NBR is computed from spectral bands centered on 866 nm and 2198 nm measured by NASA Jet Propulsion Laboratory\u2019s latest Airborne Visible/Infrared Imaging Spectrometer (AVIRIS-3). The change in NBR between pre-fire and post-fire imagery results in the dNBR index.<\/span><\/p>

Suggested Use<\/span><\/p>

The product estimates the level of burn severity for each pixel. The dNBR index is commonly used in vegetated areas, so urban surfaces may have errant solutions. Coverage of burned areas in this product is limited by the availability of pre-fire AVIRIS-3 imagery.<\/span><\/p>

Resolution<\/span><\/p>

The ground spatial resolution is approximately 3.2-m for the imagery covering the Eaton Fire and 3.2-m for the Palisades Fire. Flights occurred on 09/05/2024 and 01/16/2025.<\/span><\/p>

The dNBR burn severity levels are classified by colors. Green is unburned (dNBR < 0.1), yellow is low severity (0.1 < dNBR < 0.27), orange is moderate-low severity (0.27 < dNBR < 0.44), red is moderate-high severity (0.44 < dNBR < 0.66), and brown is high severity (dNBR > 0.66).<\/span><\/p>
