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 |
