How do sunshine recorders work?
Sunshine recorders, such as the Campbell-Stokes recorder, work by using a glass sphere to focus sunlight onto a card, burning a trace that indicates the duration of sunshine. The instrument consists of a spherical lens that concentrates sunlight onto a card, which is typically made of a heat-sensitive material. When the sun shines, the focused sunlight burns a mark on the card, creating a trace that corresponds to the duration of sunshine. The card is typically replaced daily, and the traces are analyzed to determine the amount of sunshine hours recorded.
The Campbell-Stokes recorder is a simple, yet effective instrument that has been used for centuries to measure sunshine hours. The instrument is typically installed in a location with unobstructed sunlight, and the card is replaced daily to ensure accurate recordings. The traces on the card are then analyzed to determine the duration of sunshine, which is essential for various applications, such as climate monitoring, weather forecasting, and renewable energy production. While modern electronic instruments have become more prevalent, sunshine recorders like the Campbell-Stokes recorder remain a reliable and low-cost option for measuring sunshine hours.
What are the advantages of using pyranometers to measure sunshine hours?
