Question

what is the purpose of rain gauge?​

Answer 1

Answer:

A rain gauge is a meteorological instrument to measure the precipitating rain in a given amount of time per unit area. The instrument consists of a collection container which is placed in an open area. The precipitation is measured in terms of the height of the precipitated water accumulated in the container per given time and is expressed in millimetres. Since the same amount of rain precipitation is assumed to be occurring around the container, the area of collection is not a factor. However, it should not be too small, neither should it be too large. Due to spatial uniformity of rainfall, 1 mm of measured precipitation is the equivalent of 1 L of precipitated rain water volume per metre squared

please mark me branliest

Answer 2

a rain gauge basically collects water falling on it and records the change overtime in the rainfall depth which is usually Expressed in mm plz mark as brain list
