Purpose: Radiometric, vicarious calibration test site with large homogenous regions
Description: Dry-lake playa, spatially homogeneous, consisting of compacted clay-rich lacustrine deposits forming a relatively smooth surface compared to most land covers, although it has a lower spatial uniformity compared to the Ivanpah and Lunar Lake sites. The surface composition is comparable to those of Ivanpah and Lunar Lake; however, all three sites suffer from the presence of iron absorption (Fe3+) in the visible part of the spectrum, characteristic of playas in this region of the United States.

Google Earth: Slightly patchy (in color and intensity) across the playa.
Support Data: Strong linear road features and oil drilling structures (no lat/long. available)
Suitability: Recommended for 15-m GSD and larger, VisbleUV to SWIR. Solar reflective and emissive, sub-meter to 2-km GSD
Limitations: Soft surface composition, spatial and spectral variation, possible hot spot effects, periodic snow and water, cloud cover increases in winter, remote location for ground-based studies
