Lake Tahoe is a large, deep lake situated in a granite graben near the crest of the Sierra Nevada Mountains on the border of California and Nevada. It is the second deepest lake in the United States with average depth of 333 meters (m); length of 35 k; width of 19 km, surface area of about 490 km2, and total volume of approximately 156 km3 . Due to its depth, the lake does not freeze during the winter season, as temperatures vary from about 4 to 20 degrees C throughout the year. Lake Tahoe also has high water clarity and is at a high altitude, which makes it an ideal target for thermal sensor calibration. NASA’s Jet Propulsion Laboratory (JPL) has operated buoys on Lake Tahoe for many years .
Lake Tahoe is a radiometric and vicarious calibration site with buoy data used as in-situ measurements to validate the accuracy of Landsat sensors. The site has also been used for Landsat 8 Thermal Infrared Sensor (TIRS) vicarious radiometric calibration  and for validating in-flight calibration accuracy of the Moderate Resolution Imaging Spectroradiometer (MODIS) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) polar orbiting satellite sensors . In a recent study, the water properties of this lake have been analyzed using the Visible Infrared Imaging Radiometer Suite (VIIRS) .
