As the sun blazes across the sky, the hot image of the sun traces a scorching path on the paper. The provided sunshine recorder is developed to analyze the wind flow during year & researches. Many old burn cards that were sitting in drawers in observatories and universities for decades are now being used by researchers to study and compare the amount of solar radiation reaching the Earth, and even the cloud type and thickness in the past. The instrument must be pre-set for a given latitude. As the sun moved across the sky, the beam scorched a path across the wood. A pyranometer is used for measuring global radiation.
