AI-generated Key Takeaways
-
This Landsat 4 TM Collection 1 Tier 1 32-Day NBRT Composite dataset is deprecated and has been replaced by a newer version (LANDSAT/COMPOSITES/C02/T1_L2_32DAY_NBR).
-
The dataset covers the period from August 13, 1982, to November 17, 1993, and includes a Normalized Burn Ratio Thermal (NBRT) index calculated from Near-IR, Mid-IR, and Thermal bands.
-
Composites are created from all scenes within each 32-day period, prioritizing the most recent pixel for the composite value.
-
Landsat data is public domain and can be freely used, but requires acknowledgement of the USGS as the data source.
-
The dataset is available on Google Earth Engine, a platform for geospatial analysis.

Description
These Landsat 4 TM Collection 1 Tier 1 composites are made from Tier 1 orthorectified scenes, using the computed top-of-atmosphere (TOA) reflectance. See Chander et al. (2009) for details on the TOA computation.
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 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.
