The USGS has developed research-quality, applications-ready Level-2 and Level-3 science products, as well as Analysis Ready Data (ARD) that can be used to monitor, assess, and project how changes in land use, land cover, and land condition affect people and nature.
U.S. Analysis Ready Data (ARD)
Landsat Collection 2 U.S. 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.

Level-2 Science Products
Level-2 Science Products are time-series observational data of sufficient length, consistency, and continuity to record effects of climate change, and serve as input into Landsat Level-3 Science Products.
| Product | Collection |
| Landsat Surface Reflectance (Landsat 4-9, worldwide) Measures the fraction of incoming solar radiation that is reflected from Earth's surface to the Landsat sensor |
C2 |
| Landsat Surface Temperature (Landsat 4-9, worldwide) Represents the temperature of the Earth's surface in Kelvin (K) |
C2 |
| Landsat Surface Reflectance-Derived Spectral Indices (Landsat 4-9, worldwide) Vegetation, moisture, burn ratio, and snow measurements data |
C2 |
| Provisional Aquatic Reflectance (Landsat 8-9, worldwide) Measures the spectral distribution of visible solar-reflected radiation upwelling from the upper water column |

Level-3 Science Products: Analysis Ready Data (ARD) Inputs
The following Level-3 science products represent biophysical properties of the Earth's surface and are generated from Landsat U.S. Analysis Ready Data (ARD) inputs.
| Product | Collection |
| Dynamic Surface Water Extent (Landsat 4-9, Conterminous U.S., Alaska, Hawaii) Describes the existence and condition of surface water |
C2 |
| Fractional Snow Covered Area (Landsat 4-9, northern and wester Conterminous U.S., Alaska) Indicates the percentage of a pixel covered by snow |
C2 |
| Burned Area (Landsat 4-8, Conterminous U.S.) Represents per pixel burn classification and burn probability |

Level-3 Science Products: Scene-based Inputs
The following Level-3 science products are generated from Landsat Level-2 scene-based inputs.
| Product | Collection |
| Provisional Actual Evapotranspiration (Landsat 4-9, Worldwide) The quantity of water that is removed from a surface due to the processes of evaporation and transpiration |
