what is rain gauge??
Rain Gauge The weather instrument called a rain gauge, measures the amount of rainfall. The way the rain gauge works is, water droplets fall into the rain gauge and then the amount of rainfall is measured with a type of measuring instrument, such as a ruler. You have to make sure that you look straight at eye level, when you look at the water line inside of the container. The rain gauge works better when it’s NOT hidden under trees or houses, because you don’t want anything getting in the way of the falling rain. The Chinese government recorded the rainfall during Chou’s ruling of China, over 3000 years ago! Also, around 400 B.C. (before Christ) rainfall was measured and recorded in India. These rainfall measurements were used for farming. Rain gauges were also used in Korea around 1442 A.D. which means after the death of Christ.
