How do Landsat Collection 2 Level-2 products compare with products from Collection 1?

Landsat Collection 2 Level-2 Surface Reflectance and Surface Temperature science products are scene-based, produced within the standard processing system, and available to download directly from EarthExplorer. Collection 2 Level-2 products are available for Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8-9 OLI/TIRS data acquired from 1982 to present. Landsat MSS 1-5 data are not currently available as Level-2 products.

Landsat Collection 1 Level-2 products are only available via on-demand processing (Surface Reflectance, scene-based), or within Landsat Collection 1 U.S. Analysis Ready Data (ARD) (tile-based). Collection 1 Level-2 products are available from 1984 to December 31, 2021, when new Collection 1 processing ceased.

Landsat Collection 2 Level-2 products require Landsat Collection 2 Level-1 scenes that are processed to Tier 1 or Tier 2, as well as additional auxiliary data. The Landsat Collection 2 Generation Timeline shows the typical processing timeframe for each active satellite.
