The weather instruments are :
A rain gauge measures the amount of rainfall.
Rainfall is measured in millimetres (mm).
A rain gauge is made up of a funnel and a collecting container.
The funnel is normally wide enough.
Once rain is collected it is transferred to a measuring cylinder where the readings are taken and recorded.
The rain gauge should be placed on a flat ground in an open field.
There should be no trees or buildings next to the rain gauge
