The USGS has begun production of higher-level (more highly processed) Landsat data products to help advance land surface change studies. One such product is Landsat surface reflectance data.
After extensive investigation and testing, the decision has been made to switch the TIRS Mechanism Control Electronics from the primary to redundant side on Monday, March 2, 2015.
A trio of Landsat calibration scientists—Brian Markham (NASA Goddard Space Flight Center), Jim Storey (Stinger Ghaffarian Technologies for USGS EROS) and Ron Morfitt (USGS Earth Resources Observation and Science Center) Landsat 8 Special Issue [...]
On December 19 the TIRS instrument on Landsat 8 was reconfigured due to detection of anomalous current levels associated with the scene select mirror encoder electronics. Since that time substantial testing has been conducted to isolate the root [...]
Shortly after the launch of Landsat 8, the calibration team noticed something strange: bright and dark stripes, or “banding” was showing up across certain images collected by the satellite’s Thermal Infrared Sensor (TIRS). Prelaunch testing of [...]
The Landsat calibration team published a number of papers in the SPIE Conference Volume 9218: Earth Observing Systems XIX. Our calibration team (or cal team) is a group of scientists and engineers who work together to ensure the scientific [...]
