The Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) routinely acquire earth science datasets, which are processed to orthorectified geometrically registered products by the USGS Landsat Product Generation System (LPGS). This paper will discuss the radiometric response uniformity of these products and its stability over time. Highlighted is the data analysis methodology that enables assessment of each focal plane’s sensor chip arrays’ (or modules’) response variability at levels under 0.5%. Specifically, the technique takes advantage of the overlapping FOV’s of the adjacent sensor chips. The analysis enables tracking the stability of the chip-to-chip response variation over the mission lifetime, and detection of residual non-linearity.
