Example of Less Banding in Landsat 9 Aquatic Reflectance

These images show the lessening banding in Landsat 9 Level-2 Aquatic Reflectance Band 1 (Coastal Aerosol) for a pair of scenes acquired during the Landsat 8 / Landsat 9 underfly in November 2021. The left image is Landsat 8 Aquatic Reflectance; the middle image is Landsat 9 prior to calibration updates, and the right image is the Landsat 9 after the calibration update that was implemented into Landsat 9 Level-1 processing in early 2023.
