JNCC Sentinel-2 indices Analysis Ready Data (ARD) Normalised Burn Ratio (NBR)
Abstract
Sentinel Hub NBR description: To detect burned areas, the NBR-RAW index is the most appropriate choice. Using bands 8 and 12 it highlights burnt areas in large fire zones greater than 500 acres. To observe burn severity, you may subtract the post-fire NBR image from the pre-fire NBR image. Darker pixels indicate burned areas.
NBR = (NIR – SWIR) / (NIR + SWIR)
Sentinel-2 NBR = (B08 - B12) / (B08 + B12)
These data have been created by the Joint Nature Conservation Committee (JNCC) as part of a Defra Natural Capital & Ecosystem Assessment (NCEA) project to produce a regional, and ultimately national, system for detecting a change in habitat condition at a land parcel level. The first stage of the project is focused on Yorkshire, UK, and therefore the dataset includes granules and scenes covering Yorkshire and surrounding areas only. The dataset contains the following indices derived from Defra and JNCC Sentinel-2 Analysis Ready Data.
NDVI, NDMI, NDWI, NBR, and EVI files are generated for the following Sentinel-2 granules:
• T30UWE
• T30UXF
• T30UWF
• T30UXE
• T31UCV
• T30UYE
• T31UCA
As the project continues, JNCC will expand the geographical coverage of this dataset and will provide continuous updates as ARD becomes available.

| Title | Computation for JNCC Sentinel-2 indices Analysis Ready Data (ARD) Normalised Burn Ratio (NBR) |
| Abstract | All index equations from Sentinel-hub custom scripts (links in Related Documents). Sentinel-2 surface reflectance products are obtained from Defra and JNCC Sentinel-2 ARD CEDA dataset. ARD granules are masked using the corresponding cloud and topographic shadow masks. NBR index files are then generated in R 3.6.1 using the raster::calc function. |
