The Bureau of Meteorology apparently stopped using the sunshine recorder at a time when suitable cards for recording were difficult to obtain. The Blake-Larsen Sun Recorder is a simple and unique sensor to determine sunshine duration. The Duration of Sunlight Recorder, also known as the Campbell-Stokes Recorder, The Stokes Sphere, or simply referred to as a Sunshine Recorder is used to concentrate sunlight into a beam hot enough to burn paper. Hours per day. As well, they need strength even when wet as the cards are exposed to rain and would be useless if they disintegrated when collected on a wet day. Measuring sunshine duration – how it works Photo by Arthur Ogleznev on Unsplash When sunshine is present the glass ball would focus the rays and burn a hole through a strip of photosensitive card. How It Works. A Campbell Stokes Recorder measures sunshine. The recorder shown above was originally used at Sydney Observatory, which began weather recording in NSW, and later was passed on to the newly formed Commonwealth Bureau of Meteorology. In this device a glass sphere concentrates sunlight onto a card and the amount of scorching on the card records the amount of sunlight that had fallen on it. In the prologue, the narrator observes that after the truth about Nickel Academy comes out, “even the most innocent scene – a mess hall or the football field – came out sinister, no photographic trickery necessary.” Can you think of … How do you catch sunshine? endstream endobj startxref 0 This information is useful in meteorology, science, agriculture, tourism, and … why sunshine cards get scorched instead of burning? Note the scorching evident above the dates. Describe how a sunshine Recorder Works? the unit is designed to record hours of bright sunshine which will burn a hole through a card. Hope this helped :) As the Sun traces out different paths in the sky during the year – higher in summer and lower in winter – the cards have to be placed at different positions depending on the season.

As the light hits the sphere it is bent by an amount depending on the angle with which with it hits and and a quantity called the refractive index of the glass. It measures the intensity of sunshine on any given day the same way a thermometer measures temperature or a barometer measures air pressure. It detects sunshine duration as the human eye would do by its design and measuring principle. Campbell–Stokes sunshine recorder A device in which a glass sphere concentrates the Sun's rays on to a calibrated paper, where the resulting burns register the time and duration of sunshine. Case Study. Read about company. Use a Campbell-Stokes sunshine recorder! How It Works; Spherical lens focuses light on sensitized paper. In contrast with present methods, it even determines sunshine duration with dusk and dawn. How does a sunshine recorder work? The sunlight burns or chars a mark onto the card. Sunshine is recorded with a simple, yet clever device, called a Campbell-Stokes recorder, the design of which goes back to 1879. Discover Kings Cinema, an art deco cinema in the style of the 1930s installed at Powerhouse Museum. Maybe that connection led to the Observatory placing the order for the sunshine recoder with Fuess. A pyranometer is used for measuring global radiation. In fact many are still in use to this day. The Bureau of Meteorology does not seemed to have released the figures for February as yet, but for January 2011 it states ‘Sydney Airport recorded an average of 7.6 hours of sunshine per day during this month, which is average for January.’ Melbourne recorded the same average hours of sunshine in January, but there it was less than the climate average of 8.1 hours. This antique technology, called a Campbell-Stokes sunshine recorder, is one of the simplest meteorological device that’s still in use today. There is more information on the Powerhouse Museum collection database. How Do Digital Thermometers Work? An ordinary lens would be unsuitable for as the Sun moves across the sky sunlight would hit the lens at varying angles.

It is a glass sphere which concentrates the rays of the sun on to a spot on a strip of paper which is marked in hourly intervals. SUNSHINE RECORER • A sunshine recorder is a device that records the amount of sunshine at a given location. The paper burns when the sun is shining. The card for recording must be placed at that distance of 1/4 of the diameter or width of the sphere from its surface. To only way to use a simple lens and still receive a meaningful result would be to make the lens follow the motion of the Sun across the sky from east to west, but that would be a much more complex device. Dincy, It’s not so much where but what orientation to place it in. a Fig. How much sunshine is there? The general design of anemometers is simple.

One way that the duration of sunlight is measured is through a Campbell-Stokes sunshine recorder. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page. sunshine recorders using photosensors as radiation detectors have been developed. Obviously it needs to be placed where the Sun can shine onto the glass sphere from sunrise to sunset. The Campbell–Stokes recorder (sometimes called a Stokes sphere) is a type of sunshine recorder.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. The results provide information about the weather and climate as well as the temperature of a geographical area. The sunshine recorder is a kind of sundial, which the corre- sponding burning point should indicate the true solar time. It is comprised of a glass canister or sphere that directs sunlight onto a card that is treated with a special chemical. As the sun moves across the sky a corresponding hole would be made in the card. Campbell sunshine recorder c. 1880 (Science Museum / Science and Society) John Francis Campbell (1821-1885), of the Hebridean island of Islay, designed the apparatus pictured above. As discussed here, it is a relatively simple matter to trace the path of a beam of light inside a glass sphere.

The instrument must be pre-set for a given latitude. In this device a glass sphere concentrates sunlight onto a card and the amount of scorching on the card records the amount of sunlight that had fallen on it. The hours of bright sunshine are recorded by the rays of the sun passing through the sphere, which undergo focus and burn a hole through the card placed behind it.
