energy reaching TIRS

Schematic showing the three major energy paths (the source, the background and the dark signal) reaching the Landsat 8 TIRS detectors and contributing to the recorded raw signal. Image credit: Montanaro, et al.

Feb 19, 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)—edited the recent Landsat 8 Special Issue of the journal Remote Sensing.

From the editors:
Landsat 8 (formerly LDCM) was launched on February 11, 2013. There are two new sensors on Landsat 8: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). Unlike historically used whisk broom scanners (as on the ETM+ sensor on Landsat 7), these new sensors are examples of push broom technology. In addition to having new instruments that have their individual characteristics and calibrations, the change in sensor technology produces significant differences in data characteristics and quality. This Special Issue aims to provide the user community with a good understanding of the radiometric and geometric properties of the Landsat 8 instruments and their data. This understanding will enable the community to effectively use the data in conjunction with data from other earlier Landsat sensors.
