AI-generated Key Takeaways
-
This dataset provides Landsat Collection 2 Tier 1 Level 2 annual composites of the Normalized Burn Ratio Thermal (NBRT) index from 1984 to the present.
-
The NBRT index, used to assess burn severity, is derived from Near-IR, Mid-IR, and Thermal bands and ranges from -1.0 to 1.0.
-
Annual composites include all scenes from each year with the most recent pixel value used.
-
Landsat datasets are public domain, requiring acknowledgement of the USGS as the data source.

Description
These Landsat Collection 2 Tier 1 Level 2 composites are made from Tier 1 Level 2 orthorectified scenes.
The Normalized Burn Ratio Thermal (NBRT) index is generated from the Near-IR, Mid-IR (2215 nm), and Thermal bands, and has a range from -1.0 to 1.0. See Holden et al. (2005) for details.
These composites are created from all the scenes in each annual period beginning from the first day of the year and continuing to the last day of the year. All the images from each year are included in the composite, with the most recent pixel as the composite value.
Notes:
The code used to create the composites can be seen here.
Only daytime images with WRS_ROW < 122 are included.
For Landsat 7 , images after 2017-01-01 are excluded due to orbital drift.
For Landsat 8, images before 2013-05-01 are excluded due to pointing issues.
