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