Landsat Calibration and Validation

The USGS ECCOE Landsat Cal/Val Team, along with their NASA counterparts, maintains primary responsibility for radiometric and geometric characterization and the calibration and validation of the Landsat instruments and spacecrafts. This work includes both the ongoing operations of active Landsat missions, as well as the retired Landsat missions.

The USGS/NASA Landsat Cal/Val Team supports Landsat Missions with preflight instrument and spacecraft characterization and calibration. The latest calibration and validation efforts have been focused on the instruments and data acquired by the Landsat 9 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) instruments. Landsat 9 was launched on September 27, 2021, and Level-1 data became available on February 11, 2022. 

Visit the Landsat Missions Landsat Calibration & Validation page for more details on the work done by ECCOE to support the Landsat.


ECCOE Landsat Quarterly Calibration and Validation Reports

The ECCOE Landsat Cal/Val Team continually monitors the geometric and radiometric performance of active Landsat missions and makes calibration adjustments as needed to maintain data quality at the highest level. Results of the analysis are summarized in USGS Open File Reports that will be published quarterly and posted here below.
