The temperature measured by seven sensors (CTN) in a bin of barley (from 1 to 7 m height). The bin has a diameter of 6.3 m and a height of 8 m. Air is blown through the grain by a fan, from the bottom to the top, during ~5 days. This graph was used for a presentation with a color BARCO equipment. Using a black background helps to differentiate many different light colors used for the waves.
