Page Summary
-
This dataset contains Landsat 5 TM composites made from Level L1T orthorectified scenes, using top-of-atmosphere (TOA) reflectance, and is superseded by LANDSAT/LT05/C01/T1_32DAY_BAI.
-
The Burn Area Index (BAI) in this dataset measures the spectral distance of each pixel from a reference spectral point to emphasize the charcoal signal in post-fire images.
-
The composites are created from all scenes in each 32-day period, with the most recent pixel used as the composite value.
-
This dataset is complete as the USGS is no longer producing Pre-Collection Landsat as of May 1, 2017, and users should switch to a Collection 1-based dataset.
-
Landsat datasets are in the public domain and may be used, transferred, or reproduced without copyright restriction, with acknowledgement of the USGS as the data source.

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 32-day period beginning from the first day of the year and continuing to the 352nd day of the year. The last composite of the year, beginning on day 353, will overlap the first composite of the following year by 20 days. All the images from each 32-day period are included in the composite, with the most recent pixel as the composite value.
