AI-generated Key Takeaways
-
This dataset of Landsat 5 TM composites is superseded by a newer version and is complete as of May 1, 2017.
-
The composites are made from Level L1T orthorectified scenes using top-of-atmosphere (TOA) reflectance.
-
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 from all scenes in each 8-day period, with the most recent pixel used for the composite value.
-
Landsat datasets are in the public domain and can be used without copyright restriction, with acknowledgement of USGS as the data source recommended.

Description
These Landsat 5 TM composites are made from Level L1T orthorectified scenes, using the computed top-of-atmosphere (TOA) reflectance. See Chander et al. (2009) for details on the TOA computation.
As of May 1, 2017, the USGS is no longer producing Pre-Collection Landsat, and therefore this collection is complete. Please switch to a Collection 1-based dataset. See this documentation page for more information.
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)](https://www.tandfonline.com/doi/abs/10.1080/01431160210153129 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.
