Its a tool called a rain gauge.
A rain gauge is used to measure precipitation :D
Rain Gauge measures precipitation
The four basic instruments used by meteorologists include the thermometer, the barometer, the anemometer and the hygrometer. The thermometer is used to measure temperature, as you might have guessed. The barometer is used to measure barometric (atmospheric) pressure. The anemometer is used to measure wind speed, and the hygrometer is used to measure relative humidity.A beginning investigator wishing to review the tools of the meteorologist will start with these four basic instruments. There are, however, many other instruments and observation systems used by meteorologists, and a list of them can be found by using the link below.
Its Rain Gauge
A radar measures winds and precipitation inside a storm
It measures precipitation in its liquid state.
Rain gauze measures precipitation at the given place and time.
It is very difficult to measures the precipitation in the ocean. This is because the ocean is far too large.
A rain gauge measures in inches because it collects and measures the amount of precipitation that has fallen in an area.
A balance measures mass.
Examples of geographical instruments include compasses for navigation, theodolites for measuring angles in surveying, and GPS devices for tracking location using satellites. These instruments help people collect data, make maps, and navigate in the field.
