What Landsat data products are available?

There are several Landsat data products that are useful for science applications and land use/land change studies: 

Landsat Level-1 Science Products - Each Level-1 scene includes individual spectral band files, a metadata file, and additional ancillary files. These products cover worldwide scenes. 

U.S. Landsat Analysis Ready Data (ARD) - Uses Landsat Collections Level-1 data as input to provide data that is processed to the highest scientific standards and placed in a tile-based structure to support time-series analysis. U.S. ARD are available for the conterminous United States, Alaska, and Hawaii. Landsat Collection 2 U.S. ARD products are processed to a common tiling scheme, which is modified from the Web-Enabled Landsat Data (WELD) system. This grid is different from the Landsat satellites path and row. 

Landsat Level-2 and Level-3 Science Products - Processed time-series observational data of sufficient length, consistency, and continuity to record effects of climate change. These products cover worldwide scenes. 

  • Level-2 Science Products: surface reflectance, surface temperature, surface reflectance-derived spectral indices, and provisional aquatic reflectance. 

  • Level-3 Science Products: dynamic surface water extent, fractional snow covered area, burned area, and provisional actual evapotranspiration.
