Dried-Out Lake Used As Massive White Balance For Satellites

Just like when photographers use a piece of white paper to calibrate their cameras, British scientists are using this dried-out Turkish lake to set the white balance of Earth observation satellites.

Lake Tuz, in south Turkey, dries to the stark-white you see in the photo above every July-August, joining seven other locations around the world which are being used by scientists to check satellites' cameras are in check.

From the August 14-25, scientists will be analysing the whiteness and reflectivity of Lake Tuz from the ground, and comparing it to what they've snapped up above. [NPL via PopSci]
