Page Summary
-
This dataset contains Landsat 7 Collection 1 Tier 1 8-day composites, now superseded by LANDSAT/COMPOSITES/C02/T1_L2_8DAY_BAI.
-
The composites are generated from Tier 1 orthorectified scenes using computed top-of-atmosphere (TOA) reflectance.
-
The Burn Area Index (BAI) band, derived from Red and Near-IR bands, measures spectral distance to a reference point and emphasizes charcoal signals in post-fire images.
-
These composites are created from all scenes within each 8-day period, with the most recent pixel used as the composite value.
-
Landsat datasets are public domain, and use should include acknowledgement or credit to the U.S. Geological Survey.

Description
These Landsat 7 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 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.
