TIRS’s degraded radiometric response has slowed and the Landsat Calibration and Validation Team have produced new TIRS calibration parameters. These new TIRS calibration parameters will be used to reprocess all Landsat 8 data acquired from November 1, 2020 to February 19, 2021 into Collection 1 and Collection 2 Level-1 tiered products.

This Landsat 8 reprocessing effort will begin on March 1, 2021. The reprocessing will start with the most recent data on February 19, 2021, and work backwards to November 1, 2020. As a result, reprocessing of the Level-1 products will propagate through to all Collection 1 and Collection 2 Level-2 products, Collection 1 U.S. Analysis Ready Data, and Collection 1 Level-3 Science Products for the same time period. These scene or tiled data products will become available on all USGS data access portals upon successful completion.

The USGS recommends that users consider replacing Landsat 8 data and any subsequently derived products from November 1, 2020 to February 19, 2021 with these newly reprocessed data products. Please note, the Product ID contains the processing date that will facilitate identification of all scenes or tiles included in this reprocessing effort.

Upon completion of this effort, the nominal two-week processing schedule of Landsat 8 tiered Collection products will resume.
