From Wikipedia A rain gauge (also known as a udometer or a pluviometer [Pluviograph ] or a cup) is a type of instrument used by meteorologists and hydrologists to gather and measure … An instrument that collects and measures rainfall is called a rain gauge 2. Other gauges collect the rain and weigh it, later converting this measurement into inches. Once the snow is collected, the container is removed. Many Automated Surface Observing System (ASOS) units use heated tipping buckets to measure precipitation.[17]. The precisely dimensioned (b) measuring tube has a capacity representative of only 2 inches (50.8 millimeters) on flat level ground. This is built to British Meteorological Office specifications, ensuring accurate rainfall collection and measurement. Meteorologists use weather maps to forecast the weather. It is used in meteorology as an additional tool of the weather forecast and the climatology for the purpose of long-term statistics of precipitation. Tipping Bucket Rain Gauge. Weather radar is an essential weather instrument used to locate precipitation, calculate its motion, and estimate its type (rain, snow, or hail) and intensity (light or heavy). It is usually measured in millimetres.Rain gauge is a meteorological instrument for determining the depth of precipitation (usually in mm) that occurs over a unit area (usually one metre square) and thus measuring rainfall amount. Leaf Wetness Sensor. An instrument used to measure atmospheric … This type of rain gauge cannot provide the information regarding when exactly the rain commenced, the rain ended, what is the intensity of rainfall and how much intensity of rainfall … Instrument For Measuring Rainfall. Evapotranspiration and precipitation are the key variables for the exchange of water between the soil and the atmosphere. One of the components is a copper catchment container, and the other one is a gauge itself. Nonrecording rain gauges give the amount of rainfall only. A rain gauge is the instrument used to measure rainfall. Precipitation gauges (often known as rain-gauges) are the most common instruments used to measure precipitation. Any excess precipitation is captured in the outer metal cylinder.
