Lunar Lake Playa

|
The Lunar Lake Playa, Nevada (LLPN), site is located approximately 300 miles north of Las Vegas. It is a dry-lake playa surrounded by mountains and is relatively flat with high reflectance (beyond 0.7 micrometers). The site has an approximately 2 km × 4.5 km area where terrain elevation varies less than 1 to 2 m. The area is very spatially uniform, with portions varying in reflectance by less than 0.5 percent. The central region of this area (0.5 km × 0.5 km) represents a smooth and homogeneous characteristic [1], but the temporal variation may impact time-series analysis.
LLPN has been used for medium- to high-resolution satellite sensor calibration, such as for IKONOS, SPOT High Resolution Stereoscopic, QuickBird, etc. As the usable area of this site is relatively small, it is not suitable for calibration of low spatial resolution sensors. LLPN is frequently used for vicarious calibration of sensors to measure solar reflected radiation due to its radiometric spatial uniformity. The site is a target for validation of small footprint sensors such as Landsat and ASTER.
