Uyuni Salt Flats
|
|
The Uyuni Salt Flats site is located within Salar de Uyuni, the world's largest salt flat, in southwest Bolivia. The stable area within the test site area extends to at least 25 km × 25 km, with an altitude of 3650 meters. This site is characterized by low atmospheric aerosol loading and a high probability of cloud-free weather [1].The climate is cold and dry, has low relative humidity levels, and low precipitation.
This site is considered very stable with higher reflectances (>0.3) at the short wavelength range of <600 nanometers (nm) [1].
