Science Center Objects

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.

Landsat Level-2

Surface Reflectance

Measures the fraction of incoming solar radiation that is reflected from Earth's surface to the Landsat sensor. 

Provisional Surface Temperature 

Represents the temperature of the Earth's surface in Kelvin (K). 

Landsat Level-3

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

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.
