The Campbell–Stokes sphere is used to record sunshine. It was invented by John Francis Campbell in 1853 and modified in 1879 by Sir George Gabriel Stokes.
The original design by Campbell consisted of a glass sphere set into a wooden bowl with the sun burning a trace on the bowl.
Stokes’s refinement was to make the housing out of metal and to have a card holder set behind the sphere.
