Chesapeake Bay is the Nation's largest estuary and its restoration and protection is a priority. The USGS provides scientific information to help manage this vital ecosystem. As part of that role, staff at the USGS Earth Resources Observation and Science (EROS) Center created this true color composite image.
Landsat Surface Reflectance
Landsat Surface Reflectance measures the fraction of incoming solar radiation reflected from Earth's surface to the Landsat sensor.

Return to Landsat Science Products Overview
Surface reflectance improves comparison between multiple images over the same region by accounting for atmospheric effects such as aerosol scattering and thin clouds, which can help in the detection and characterization of Earth surface change. Surface reflectance is generated from Level-1 inputs that meet the <76 degrees Solar Zenith Angle constraint and include the required auxiliary data inputs to generate a scientifically viable product.
Please note: To ensure accurate analysis of Landsat Surface Reflectance data, it's essential to apply the appropriate scaling factors to convert digital numbers (DN) to meaningful reflectance values.
Landsat surface reflectance data are available globally for the following instruments:
- Landsat 9 Operational Land Imager 2 (OLI-2): October 2021 to present
- Landsat 8 Operational Land Imager (OLI): April 2013 to present
- Landsat 7 Enhanced Thematic Mapper Plus (ETM+): July 1999 to April 2022
- Landsat 5 Thematic Mapper (TM): March 1984 to May 2012
- Landsat 4 Thematic Mapper (TM): July 1982 to December 1993
Please note that Level-2 Multispectral Scanner (MSS) surface reflectance products will only become available upon the maturity of an operational atmospheric compensation algorithm which satisfies the USGS Landsat program requirements.
