Landsat Missions

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

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.

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

Level-3 

Level-3 science products represent biophysical properties of the Earth's surface and are generated from U.S. Landsat Analysis Ready Data (ARD) inputs.

Dynamic Surface Water Extent  Describes the existence and condition of surface water.
Fractional Snow Covered Area  Indicates the percentage of a pixel covered by snow.
Burned Area  Represents per pixel burn classification and burn probability.
Provisional Actual Evapotranspiration The quantity of water that is removed from a surface due to the processes of evaporation and transpiration
