Abstract
Landsat 8 collects the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS) data and stores them at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center. The Landsat Product Generation System (LPGS) was designed to process both OLI and TIRS acquisitions and combine them into the 11-band Level 1 Terrain (L1T) standard products. Processing parameters and various scene statistics are stored and used for radiometric and geometric assessments of generated products. In this paper, we discuss application of several processing changes and instrument calibration updates to product generation that have been performed over the first 10 years of the mission life to address variations in instrument responsivity and effects of spacecraft and sensor anomalies. In addition, we provide examples of radiometric and geometric performance assessments to demonstrate product calibration stability over time. After 10 years on orbit, both Landsat 8 sensors continue to perform very well and provide high quality products to the user community.
