Campbell Stokes Sunshine Recorder – Temperate

The Campbell-Stokes Sunshine Recorder is manufactured by Fairmount Weather Systems to the specifications of the British Meteorological Office and is used extensively by government meteorological services world wide. In 1964 the Campbell-Stokes Sunshine Recorder was adopted by the World Meteorological Organisation (WMO) as their Interim Reference Sunshine Recorder for use in all member countries.

The sphere, made of well-annealed colourless optical glass is securely clamped on a semi-circular metal arc by means of two bosses attached precisely across a diameter and located by an adjusting screw onto the ball ended boss.

Also mounted on the arc is a bowl of spherical section machined from gunmetal. This bowl has the shape of a belt cut from a hollow sphere and contains three overlapping pairs of grooves in which record cards suitable for different seasons can be inserted and secured by a screw.

The metal arc is mounted in a grooved slide to permit the inclination of the sphere and bowl to be adjusted for geographical latitude and the slide is mounted on a T-shaped metal base which is supported on levelling screws on a fixed metal sub-base.

The Campbell-Stokes Sunshine Recorder is perfect for Meteorological and agrometeorological use. It is also a beautiful gift for private use.
