A rain gauge basically collects water falling on it and records the change over time in the rainfall depth, which is usually expressed in mm. You can get much more detailed information with disdrometers.
What Are Rain Gauges Used For?
A rain gauge is a simple scientific instrument used to measure the amount of liquid precipitation over a set period of time. The first rain gauges were created in the early 1800s, and they have been used in weather forecasting ever since.
Today, rain gauges are still an important tool for meteorologists as they help to predict the amount of rainfall in a given area. Most rain gauges consist of a funnel that collects the rainwater and funnels it into a measuring container.
The container is typically made of glass or plastic, and it is marked with graduated lines that indicate the amount of precipitation that has been collected. The measurements are then recorded in inches or millimeters.
Rain gauges are important tools for measuring precipitation because they help to determine the amount of water that is available for plants and animals. They also help to predict floods and droughts.
In some cases, rain gauges are also used to measure the amount of snowfall. There are a few different types of rain gauges, including automatic rain gauges, which are operated by sensors, and manual rain gauges, which are operated by people.
Automatic rain gauges are more accurate than manual rain gauges, but they are also more expensive. Rain gau
