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 U.S. Landsat Analysis Ready Data (ARD) inputs.

Product Collection Description
Dynamic Surface Water Extent  C1 Describes the existence and condition of surface water.
Fractional Snow Covered Area  C1 Indicates the percentage of a pixel covered by snow.
Burned Area  C1 Represents per pixel burn classification and burn probability.

Level-3 Scene-based Inputs

The following Level-3 science products are generated from 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.
