Tuz Golu
|
|
The Tuz Gölü test site is a permanent endorheic lake located in the Central Anatolian plateau of Turkey. It is 150 km southeast of Ankara and 105 km northeast of Konya. Tuz Gölü is easily accessible as well as logistically convenient and far from the influence of any bodies of water. In the summer, 95 percent of the water in the lake dries, which results in a smooth, uniform, and flat 30-80 cm thick layer of salt over a region of 500 km2. There is no vegetation on the dry salt lake [1,2].
The vicarious calibration site is used for absolute radiometric calibration.
