Landsat Science Products

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.

We welcome your feedback on Landsat data and Landsat Science Products! Please reach out us at with any questions or comments. 


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. 

Product Collection

U.S. Analysis Ready Data (ARD) (Landsat 4-9, Conterminous U.S., Alaska, Hawaii)
Landsat Collection 2 Level-1 data that are processed into Albers-projected Level-2 Surface Reflectance and
Surface Temperature serve as inputs for generating U.S. ARD. 


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
Landsat Surface Temperature (Landsat 4-9, worldwide)
Represents the temperature of the Earth's surface in Kelvin (K)
Landsat Surface Reflectance-Derived Spectral Indices (Landsat 4-9, worldwide)
Vegetation, moisture, burn ratio, and snow measurements data
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                                                                                          
Fractional Snow Covered Area (Landsat 4-9, northern and western Conterminous U.S., Alaska)
Indicates the percentage of a pixel covered by snow


Burned Area (Landsat 4-9, 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
