U.S. Landsat 4-8 Analysis Ready Data (ARD) V1

U.S. Landsat Analysis Ready Data (ARD) are consistently processed to the highest scientific standards and level of processing required for direct use in monitoring and assessing landscape change. A fundamental goal for Landsat ARD is to significantly reduce the magnitude of data processing for application scientists, who currently have to download and prepare large amounts of Landsat scene-based data for time-series investigative analysis. U.S. Landsat ARD consists of surface reflectance (SR), top of atmosphere (TA) reflectance, top of atmosphere 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 data provenance. Landsat ARD products are available for the conterminous United States (CONUS), Alaska, and Hawaii. The data are generated in the Albers Equal Area Conic (AEA) map projection for the conterminous U.S. and Hawaii. Alaska is generated to the Alaska Albers map projection. Tiles are processed directly from Level-1 AEA scenes through Level-2 products using the World Geodetic System 1984 (WGS84) datum.
