Landsat Science Products

The USGS has developed research-quality, applications-ready, Level-2 and Level-3 science products derived from Landsat Level-1 data, which can be used to monitor, assess, and project how changes in land use, land cover, and land condition affect people and nature.


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 Description
Landsat Surface Reflectance C1 / C2 Measures the fraction of incoming solar radiation that is reflected from Earth's surface to the Landsat sensor.
Landsat Surface Temperature  C1 / C2 Represents the temperature of the Earth's surface in Kelvin (K).
Landsat Surface Reflectance-Derived Spectral Indices C1 / C2 Vegetation, moisture, burn ratio, and snow measurements data.
Landsat 8 Provisional Aquatic Reflectance C1 Measures the spectral distribution of visible solar-reflected radiation upwelling from the upper water column.

Level-3 - 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 Description
Dynamic Surface Water Extent  C1 /
C2 coming soon
Describes the existence and condition of surface water.
Fractional Snow Covered Area 

C1 /

C2 coming soon

Indicates the percentage of a pixel covered by snow.
Burned Area 

C1 /

C2 coming soon

Represents per pixel burn classification and burn probability.

Level-3 Scene-based Inputs

The following Level-3 science products are generated from Landsat Level-2 scene-based inputs. 

Product Collection Description
Provisional Actual Evapotranspiration C1 The quantity of water that is removed from a surface due to the processes of evaporation and transpiration.
