Landsat 8 32-Day TOA Reflectance Composite [deprecated]

  • This dataset, containing Landsat 8 composites from Level L1T orthorectified scenes using computed top-of-atmosphere (TOA) reflectance, is deprecated and superseded by a newer version due to the USGS no longer producing Pre-Collection Landsat as of May 1, 2017.

  • The composites are created from all scenes within each 32-day period, with the most recent pixel used as the composite value.

  • The dataset includes various bands covering different wavelengths, such as coastal aerosol, blue, green, red, near infrared, shortwave infrared, panchromatic, cirrus, and thermal infrared bands, along with a Quality Assessment band.

  • Landsat datasets are in the public domain and can be used without copyright restriction, though acknowledgement of the USGS as the data source is recommended.

Description

These Landsat 8 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.

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.
