How much sunshine was there ?

Sunshine is incredibly easy to measure.

I recall that as a schoolboy I went out to the school observatory, climbed up a staircase on the south side and removed the card strip from the Campbell Stokes Sun Recorder at the end of each day. A glass globe focussed the sun’s rays, as does a magnifying glass, and burned a line in a piece of card. The length of the charred line was then measured to record how much sunshine there had been that day – usually not a lot on a fellside  in Lancashire.
