Landsat 8 Level-1 Product Processing Resumes
The processing of Landsat 8 Level-1 products has resumed, following a brief pause due to an error that occurred during a standard calibration collect by the satellite’s Thermal Infrared Sensor (TIRS) on Friday April 21, 2023.
As reported in this April 23 Landsat Missions headline, processing of Landsat 8 data was paused while the USGS/NASA Calibration/Validation Team (CVT) analyzed the TIRS data acquired since April 21st. The CVT completed their analysis, determined that the post-recovery data met radiometric and geometric quality thresholds, and recommended that data processing of Landsat 8 Operational Land Imager (OLI)/TIRS combined products resume. These products will become available to download from EarthExplorer as they complete processing.
Landsat 8 scenes acquired during the timeframe of the error (between 6:02 AM CDT (11:02 z) on April 21, 2023 (DOY 111) and 1:28 PM CDT (18:28 z) on April 23, 2023 (DOY 113)) have been processed as OLI-only Level-1 products.
