What does pluviometer mean?
A pluviometer is an instrument for measuring rainfall, generally by determining the depth of water that has fallen during a particular period. It is a formal or technical term, while rain gauge is the everyday expression used in weather reports, agriculture, and home gardens. The instrument can take the form of a simple collecting container or a more advanced recording device that logs rainfall automatically. Accurate measurements are important in meteorology, agriculture, hydrology, and the assessment of water resources. A properly positioned pluviometer should be exposed to the open sky and kept clear of obstructions such as trees or buildings, since these can alter the amount of rain reaching it. Although less familiar than the simpler term rain gauge, pluviometer precisely identifies an instrument designed to quantify precipitation.
