Summary:
The images are normalized burn ratio (NBR) images generated from the ESA’s Sentinel-2’s Multi-Spectral imager. They were created from the Level 2A products which have been atmospherically corrected to correct atmospheric effects.
NBR is defined mathematically as (NIR – SWIR)/(NIR + SWIR) where NIR is near-infrared and SWIR is short-wave infrared. For Sentinel 2, NIR = Band 8 and SWIR is Band 12. Using these definitions, the 20-meter resolution Band 8 and Band 12 images were used to generate these products.
Finally, dNBR is simply the difference between the post-fire NBR and the pre-fire NBR. Thus, we calculated dNBR as dNBR = NBR (01/12/2025) – NBR (12/18/2024)
Suggested Usage:
For NBR, darker areas in the image represent more highly burned areas. Negative values on an image typically represent more burned areas.
