Instruments. The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.
How Is Rainfall Measured in Inches?
Rainfall is measured in inches by a variety of instruments. The most common instrument is the rain gauge, which is a cylindrical container with an open top. When it rains, the rainwater fills the rain gauge and the amount of rainfall is measured by the depth of the water in the container. Rain gauges are usually placed in an area that receives a consistent amount of rainfall. The measurements are then recorded and reported in inches.
Another instrument used to measure rainfall is a tipping bucket rain gauge. This device consists of a funnel that collects the rainwater, and two buckets that are connected to a lever. As the rainwater accumulates in the funnel, the buckets tip back and forth, and the amount of rainfall is measured by the number of times the buckets tip over. The measurements are then reported in inches.
In addition to the rain gauge and tipping bucket rain gauge, there are other instruments used to measure rainfall. These include the weighing rain gauge, the optical rain gauge, and the radar rain gauge. The weighing rain gauge is an instrument that measures the weight of the rainwater. The optical rain gauge uses a light detector to measure the amount of rainwater falling. The radar rain gauge uses a radar system to measure the amount of rain
