Landsat 4-8 Analysis Ready Data (ARD) Level-2 Tiles (Albers projection)

The Analysis Ready Data (ARD) Landsat Level-2 Tiles consist of surface reflectance (SR), top of atmosphere (TA) reflectance, brightness temperature (BT), and quality assessment (QA) data that are consistently processed using per pixel solar zenith angle corrections, gridded to a common cartographic projection, and accompanied by appropriate metadata to enable further processing while retaining traceability of data provenance. Subsequently, numerous products are derived from ARD that are used as direct inputs to monitoring and assessment activities, including maps of land cover and land cover change, spectral indices, temporal composites, and higher-level science products such as burned area, dynamic surface water extent, and fractional snow covered area.
Landsat ARD are generated in the Albers Equal Area Conic (AEA) for conterminous U.S. and Hawaii map projection. Alaska is generated to Alaska Albers map projection. They are processed directly from Level-1 AEA scenes through Level-2 products using the World Geodetic System 1984 (WGS84) datum. The products cover the conterminous United States (CONUS), Alaska, and Hawaii.
