Located in northwest Argentina in Provincia de San Juan. Used on a joint campaign with Argentina's CONAE to calibrate the satellite instruments EO-1 ALI and Hyperion as well as Landsat 7's ETM+ and Terra's ASTER. The EO-1 and ASTER site measured 16x4 20-m pixels on a 100-280 axis. ETM+ consisted of a 16x4 30-m pixel site on a 010-190 axis. The site was chosen because there was a need to calibrate the instruments aboard EO-1 immediately after the January launch, and weather conditions are favorable in the Southern Hemisphere in January.
Google Earth: Small homogeneous bright site. May be prone to saturation at high sun. Uniform areas are limited to 0.5 km by 0.5 km or less, but there are several such areas.
