The Landsat Calibration and Validation Team identified 130 Landsat 9 scenes acquired from June 20-21, 2022, over a period of nine hours, that were affected with the presence of the Moon in the data.

The presence of the Moon in deep space data causes errors in estimation of background response of the affected detectors, which leads to creation of dark streaks in Thermal Infrared Sensor (TIRS) imagery. Landsat 9 Operational Land Imager (OLI) bands are not impacted. 

The 130 Landsat 9 scenes were reprocessed on July 6, 2022. As a result, reprocessing of the Level-1 products will propagate through to all Collection 2 Level-2 products for the same period. These scenes will become available on all USGS data access portals upon successful completion. 

The USGS recommends that users consider replacing any already downloaded Landsat 9 data and subsequently derived products from June 20-21, 2022, with these newly reprocessed data products. Please note, the Product ID contains the most recent processing date that will facilitate identification of all scenes included in this reprocessing effort. 

For a list of reprocessed scenes, please visit the Landsat Collection 2 Reprocessing Events web page.  

Please contact EROS Customer Services with any questions about this reprocessing effort or the resulting data and products.
