The duration of sunshine is measured using the Campbell Stokes Sunshine Recorder.
This device consist of a solid glass sphere, about 4 inches in diameter.
The sphere concentrates the sun's rays to an intense spot on a calibrated paper, resulting in a trace or burn. As the sun blazes across the sky, the hot image of the sun traces a scorching path on the calibrated paper.
In the evening, the length of the trace is measured to determine the duration of sunshine.
