AI-generated Key Takeaways
-
These composites are made from Landsat Collection 2 Tier 1 Level 2 orthorectified scenes and provide the Burn Area Index (BAI).
-
The Burn Area Index (BAI) measures the spectral distance of each pixel from a reference spectral point to emphasize the charcoal signal in post-fire images.
-
Composites are created every 8 days using all scenes from the period, with the most recent pixel used as the composite value.
-
The dataset is available from 1984 to 2025 and includes only daytime images with WRS_ROW < 122, with specific exclusions for Landsat 7 and 8 images.
-
Landsat datasets are in the public domain and can be used without copyright restriction, with 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 Burn Area Index (BAI) is generated from the Red and Near-IR bands, and measures the spectral distance of each pixel from a reference spectral point (the measured reflectance of charcoal). This index is intended to emphasize the charcoal signal in post-fire images. See Chuvieco et al. (2002) for details.
These composites are created from all the scenes in each 8-day period beginning from the first day of the year and continuing to the 360th day of the year. The last composite of the year, beginning on day 361, will overlap the first composite of the following year by 3 days. All the images from each 8-day period 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.
