Temporary lakes and salt plains in the high plateaus of the Andes /Bolivia/ - A continuing survey of periodic hydrologic phenomena using the geostationary satellite GOES-EST
Abstract
A summary of the observational techniques and parameters during GOES and SMS satellites remote sensing of hydrologic features of Lakes Titicaca and Poopo in the Andes, together with neighboring salt plains, is presented. It is noted that the alternation of wet and dry seasons has provided ample opportunities for observing strong variations in reflected radiances. The SMS 1, 2, and GOES spacecraft sensors have been used to monitor the area, successively, since 1974. The sensors have included an IR channel operating at 10.5-12.5 microns and a visual channel at 0.55-0.75 micron. IR resolution has been 8 x 4 km, and visual, 1:1,000,000. Multitemporal comparative studies have been effected using the archived photography, revealing surface characteristics such as dry, wet, and snow-covered, along with corresponding changes over time.
