Page Summary
-
This dataset contains Landsat 4 TM annual composites using the Normalized Burn Ratio Thermal (NBRT) index and top-of-atmosphere (TOA) reflectance, available from 1982 to 1993.
-
As of May 1, 2017, this Pre-Collection Landsat dataset is no longer being produced by the USGS and has been superseded by a Collection 1-based dataset.
-
The NBRT index, generated from Near-IR, Mid-IR, and Thermal bands, ranges from -1.0 to 1.0.
-
These composites are created annually from all scenes, with the most recent pixel used as the composite value.
-
Landsat datasets are public domain and can be used, transferred, or reproduced without copyright restrictions, with acknowledgement of the USGS requested.

Description
These Landsat 4 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 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.
