Surface Reflectance Level-2 Data Products at a 30-meter spatial resolution can be ordered for Landsat 8 OLI/TIRS Collection 1 scenes. (2013-present)
Back to Products Overview
The U.S. Geological Survey (USGS) offers on-demand production of Landsat 8 Operational Land Imager/Thermal Infrared Sensor (OLI/TIRS) Surface Reflectance data through EarthExplorer. Surface Reflectance products provide an estimate of the surface spectral reflectance as it would be measured at ground level in the absence of atmospheric scattering or absorption. The Surface Reflectance products are generated at the Earth Resources Observation and Science (EROS) Center at a 30-meter spatial resolution. The EROS Science Processing Architecture (ESPA) on-demand interface corrects satellite images for atmospheric effects to create Level-2 data products. Landsat 8 Surface Reflectance data are generated from the Land Surface Reflectance Code (LaSRC). LaSRC makes use of the coastal aerosol band to perform aerosol inversion tests, uses auxiliary climate data from MODIS and uses a unique radiative transfer model. Additionally, LaSRC hardcodes the view zenith angle to “0”, and the solar zenith and view zenith angles are used for calculations as part of the atmospheric correction. Details about LaSRC and Landsat 8 Surface Reflectance data products can be found in the Land Surface Reflectance Product Guide.
The following date ranges apply to the availability of the Landsat archive for Surface Reflectance processing:
Most Landsat 8 Collection 1 Level-1 scenes in the USGS archive can be processed to Surface Reflectance. Please note the following caveats:
Order submission and completion emails provide details about data processing status and download instructions. Surface Reflectance products requested through EarthExplorer are delivered in GeoTIFF format. The original Landsat scene mapping grid, Universal Transverse Mercator (UTM) or Polar Stereographic (PS), is retained for the Surface Reflectance product. Additional Level-2 data products and format options are available when accessing ESPA directly.
Landsat 8 OLI/TIRS Surface Reflectance products are orderable through EarthExplorer. The Level-2 data set is located under the Landsat/Landsat Collection 1 Level-2 (On-demand) menu as “L8 OLI/TIRS C1 Level-2”
Select scenes in EarthExplorer using the Order Scene icon in the Results tab. Go to the Item Basket (top toolbar) or View Item Basket(below result list) to review the on-demand order. Click on L8 OLI/TIRS C1 Level-2 to expand the list to view the selected scenes and verify the product type. Select Proceed to Checkout then Submit Order to initiate the processing for Surface Reflectance products through ESPA.
