caption: It consists of a large cylinder with a funnel and a smaller measuring tube inside of it. The official rain gauge has a 50 centimeter high cylinder with a 20 centimeter in diameter funnel that collects water into a measuring tube that has exactly one-tenth the cross sectional area of the top of the funnel. The reason for the smaller measuring tube is that more precise rainfall measurements can be made due to the exaggeration of the height of water in the tube.
