The observatory has used a Campbell-Stokes sunshine recorder since January 1886. Sitting on the roof of a three-story tower, the device works just like frying an ant with a magnifying glass, as chief observer Brian Fitzgerald likes to tell groups of visiting kids. The glass sphere focuses sunlight into a narrow point.

A sunshine recorder is a meteorological instrument that measures the duration of sunshine at a specific location. It is a simple device that has been used for over a century to measure the amount of sunlight that reaches the earth's surface. The data collected from a sunshine recorder is used to calculate solar radiation, which is an.

Determining sunshine duration 130 years ago meant polishing the old crystal ball and scorching holes in strips of card. While sounding mystical the Campbell-Stokes recorder was cutting edge for its time. Due to the lack of moving parts, the Cambell-Stokes recorder was a reliable method to measure and record sunshine duration.

Sunshine recorders determine the number of hours the sun is visible each day, and the time of that visibility. A differential recorder operates on the principle of the differential heating between a blackened bulb and a clear bulb of a differential thermometer. The form was suggested by Delos Taft Maring of the U.S. Weather Bureau and improved.
CampbellStokes Recorder A Simple Device That Measures Sunshine
It uses an array of differently exposed photodiodes to estimate the intensity of direct radiation. A threshold intensity of 120 Wm-2 defines the occurrence of full sunshine. Sunshine is measured using either Campbell-Stokes sunshine recorders or modern sunshine sensors. A pyranometer is used for measuring global radiation.

The sunshine recorder was invented by no scientist, but a renowned Scottish author and scholar, John Francis Campbell, in 1853. At that time, it was common knowledge that certain transparent glass balls, that were commonly used as paper weights, behaved like "burning glass" leaving smoking holes over desks and writing paper placed near windows.

Sunshine recorders of pyrheliometric and pyranometric methods can operate at all latitudes (-90°∼90°). 2). Sensor. We have counted a total of 13 automatic sunshine recorders. One sunshine recorder has bimetallic element pairs, 2 with thermoelectric sensor, and 10 with the photoelectric sensor. Therefore, photoelectric and thermoelectric.

The sunshine recorders are classified into 7 types based on their measurement methods. The principles and structure of sunshine recorders are investigated with the structural diagram, and some algorithms for estimating SD are briefly discussed. The 6 critical parameters of the sunshine recorder are summarized; the operational costs.
