The data acquired during a recent Landsat 8 spacecraft anomaly have been validated by the USGS/NASA Calibration/Validation Team (CVT).  Many of the impacted scenes have now been processed to Level-1 products with updated Calibration Parameter Files.

On November 2, 2023, the CVT completed their assessment of the data acquired during and after the October 17, 2023 (DOY 290) anomaly, deployed the necessary calibration updates and gave approval for the data to be processed into standard Level-1 scene products, which started immediately. The Level-1 Real-Time products have been generated and are available to download (see data access information).   

The following WRS-2 Path/Rows were impacted by the anomaly:  

  • Path 64 Rows 109-119:  Level-1 products were initially generated and made available for download but have now been reprocessed using the updated CPF. Users are encouraged to verify the processing date in the Product Identifier to ensure the most current data are being downloaded. 


  • The following scenes have been processed to Level-1 products using the updated CPF:  

  • Path 80 Rows 10-24; 59-60; 68; 73-76; 98; 107-111  

  • Path 96 Rows 10-18; 43; 54-56; 61-87; 106-109; 144  


  • Data from the following scenes will be held until more analysis has been done and a corrective CPF can be employed in Level-1 processing systems:  

  • Path 112 Rows 10-30; 35-41; 52-85; 106-109; 115-117  

  • Path 128 Rows 7; 10-61; 68; 106-122; 215-218
