This page provides information about Landsat sensor anomalies that impact the mission-level data and subsequent Collections.
Landsat data are systematic, geometric, radiometric, and terrain corrected to provide the highest quality data to the user communities. Occasionally, anomalies occur, and artifacts are discovered that require research and monitoring. The Landsat Calibration and Validation (Cal/Val) team investigates and tracks anomalous data and monitors satellite sensors for changes.
For known issues from processing the data into Collection 2, please visit Landsat Collection 2 Known Issues
