Landsat Science Products

The USGS has developed research-quality, applications-ready, Level-2 and Level-3 science products that 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

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)
Measures the fraction of incoming solar radiation that is reflected from Earth's surface to the Landsat sensor
C1 / C2
Landsat Surface Temperature (Landsat 4-9)
Represents the temperature of the Earth's surface in Kelvin (K)
C1 / C2
Landsat Surface Reflectance-Derived Spectral Indices (Landsat 4-9)
Vegetation, moisture, burn ratio, and snow measurements data
C1 / C2
Provisional Aquatic Reflectance (Landsat 8-9 only)
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 4-8)
Describes the existence and condition of surface water                                                                                          
C1 / C2
Fractional Snow Covered Area (Landsat 4-8)
Indicates the percentage of a pixel covered by snow

C1 / C2

Burned Area (Landsat 4-8)
Represents per pixel burn classification and burn probability

C1 / C2

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)
The quantity of water that is removed from a surface due to the processes of evaporation and transpiration
