U.S Landsat Analysis Ready Data (ARD) browse images are displayed as false color composites, similar to Landsat Collection 1 Level-1 top of atmosphere reflectance browse images. However, unlike the Landsat Level-1 browse, no color stretch is applied and the data's 30-meter resolution is maintained.
Landsat 8 Operational Land Imager (OLI)
Landsat 8 ARD browse images are created using top of atmosphere reflectance bands 6, 5, and 4.
