Which instrument is used to measure rainfall amount and duration?

Explanation:
Measuring rainfall requires an instrument that collects precipitation and records how much fell over a set period. The rain gauge does this by catching rain in a graduated container, so you can read the depth of rainfall (the amount) and, by noting the time period over which it collected, determine how long the rain lasted (the duration). Other tools measure different weather aspects: a barometer gauges atmospheric pressure, which helps forecast weather; a hygrometer measures humidity in the air; an anemometer measures wind speed. Since only the rain gauge directly measures how much rain fell and for how long, it’s the appropriate instrument for this purpose.
