The USGS is developing research-quality, applications-ready, Level-2 and Level-3 science products derived from Landsat Level-1 data. These data can be used to monitor and assess how changes in land use, land cover, and land condition affect people and nature.

*Available now*

Level-2 Surface Reflectance - the fraction of incoming solar radiation that is reflected from Earth's surface to the Landsat sensor. 
Level-2 Provisional Surface Temperature  - represents the temperature of the Earth's surface in Kelvin (K). 

 

*Coming soon in 2019*

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:  

Level-3 Dynamic Surface Water Extent describes the existence and condition of surface water.
Level-3 Fractional Snow Covered Area - indicates the percentage of a pixel covered by snow.
Level-3 Burned Area represents per pixel burn classification and burn probability.

Level-3 sample data products are available to download

Available Landsat Science Products

Currently, Surface Reflectance data, Provisional Surface TemperatureSurface Reflectance-derived spectral indices are available for most Landsat scenes acquired from August 1982 to present. Level-3 Dynamic Surface Water Extent, fractional Snow Covered Area, and Burned Area products will become available as they complete development.

Metadata

Landsat Science Products Metadata contain significant amounts of information that can be used to locate specific data files in the archive inventory, and inform users of certain data product characteristics. The metadata files may vary based on which interface is being used to order the product.

Quality Assessment

Lansdat Surface Reflectance Quality Assessment (QA) bands provide users an indication of whether the integrity of Surface Reflectance data have been affected by instrument artifacts, production software updates, or atmospheric conditions. 

Data Access

Processing requests for Surface Reflectance, Surface Reflectance-derived spectral indices, and Surface Temperature can be submitted at no charge. The Landsat Science Products Access page provides information on the ordering interfaces.
